clang-tidy: Suppress unused variable warnings

The following errors were reported during clang-tidy enablement due to
multiple unused variables. This temporary fix suppresses the warnings
using a pragma approach until a permanent solution is
implemented.

Changes:
- Commented out unused variables to suppress the -Wunused-variable
warnings.

psutils: Add new functions to AEI Updater class

The following functions handle the critical stages of firmware update,
including validation, reading, preparation, and reboot verification.
Error handling and logging are incorporated to isolate issues during the
update.

getFirmwarePath()
Retrieves the firmware file path from the image directory. Uses
getFWFilenamePath to fetch the path. Logs an error if the firmware path
is not found and returns an empty string otherwise returns firmware
path.

isFirmwareFileValid()
Validates the firmware file at the given path using validateFWFile.
Ensure the firmware file exists and meets requirements before proceeding
with the update. Logs an error if validation fails.

openFirmwareFile()
Opens the firmware file at the specified path for reading in binary
mode. Logs an error if the file cannot be opened.

readFirmwareBlock()
Reads a block of data from the firmware file.Uses readFirmwareBytes to
read the specified number of bytes.

prepareCommandBlock()
Prepares a command block for writing firmware data to the PSU. Adds
metadata, data, and a CRC8 checksum. Packages firmware data in a format
suitable for I2C transmission.

ispReboot()
Sends a reboot command to the status register to apply new firmware.

ispReadRebootStatus()
Reads the reboot status from ISP, returns true for success otherwise
false.

Tested:
- Validated that the firmware path retrieves the correct file.
- A validation error is logged when the file is empty or path is
incorrect.
- Removed read permission on the firmware file and verified that an
error was logged.
- Verify the block of data read as specified in the specification.
- Printed the command block and verified that the command and data are
ready to be sent to the PSU via I2C.
- Downloaded the firmware and verified that the command block, ISP
reboot and reboot status are working as expected.

psutils: Partial AEI Updater class

The AeiUpdater class within the aeiUpdater namespace, responsible for
updating AEI PSU firmware via I2C communication. The code focuses on
executing various stages of the firmware update process, ensuring each
step performed and validated correctly. The following partial functions
of the key component of the class:

doUpdate()
This method initiates the firmware update process. It checks and sets
the ISP (In-System Programming) mode using writeIspKey(),
writeIspMode(), and writeIspStatusReset().

writeIspKey()
Unlocks the ISP by writing a specific key to the KEY_REGISTER. Handles
exceptions for any I2C communication errors and logs the failure.

writeIspMode()
Sends a command to enter ISP mode and checks the status register.
Retries on failure, with a maximum retry limit. Checks the status
register to confirm the mode has been set. Logs any I2C errors
encountered.

writeIspStatusReset()
Resets ISP status register, clearing any existing status flags. Verifies
the reset by reading the status register, retrying as needed. Logs any
I2C errors encountered.

Test:
Tested the function listed in the class on a system with AEI PSU:

- Validated the PSU ISP key was accepted and no error logged.
- Validated an error was logged when I used wrong key.
- Validated the PSU entered to ISP mode by reading back status register
and confirmed the bit is set.
- Validated the PSU status reset by reading the back status register and
confirmed the bit is set.

psutils: Move functions from updater to utils

Move common, utility functions from updater.*pp to utils.*pp. This will

Also update --get-version to provide a single getVersion() function that
handles the existence of the psu.json file as a low-level implementation
detail.

* Verified --get-model still works

psutils: Do not pad PSU version with blanks

When `psutils --get-version <inventory_path>` is run, it returns the
firmware version for the specified PSU inventory path.

If no psu.json file is found, the PSU I2C bus and address are obtained
from D-Bus. The PSU version is then obtained from a file in sysfs.

The contents of the sysfs file are currently treated as VPD. Invalid
characters are replaced with spaces, and the value is padded with spaces
if needed to reach an expected VPD length.

If an error occurs trying to read the sysfs file, the version is
initially set to "". However, since it is being treated as VPD it is
later padded with blanks. Since the version is not an empty string, it
is treated as valid by psutils and the PSU code update application.
This causes subsequent code update issues.

Modify psutils so that the contents of the sysfs file are treated as a
simple string. If an error occurs, set the version to "". This will
cause psutils and the PSU code update application to correctly conclude
that an error occurred and the version is not valid.

Tested:
* psutils --get-version
* psu.json file exists
* Test where getting the version works
* Verify file contents are obtained
* Verify psutils prints out the version
* Verify psutils exits with a return code of 0
* Test where getting the version fails
* Verify exception is written to the journal
* Verify psutils prints out an empty string
* Verify psutils exits with a return code of 1
* psu.json file does not exist; PSU information is obtained from D-Bus
* Test where getting the version works
* Verify file contents are obtained

Only build tests if -Dtests=enabled specified

A meson build option named 'tests' is defined for this repository. It
indicates whether gtest/gmock tests should be built.

However, some tests are currently always built even if -Dtests=enabled
isn't specified. This causes build errors in some environments where
gtest and gmock are not available.

Modify meson.build files to only descend into 'test' subdirectories and
build test cases if -Dtests=enabled was specified.

Create libi2c_dev_mock.a to solve linker errors

The i2c::create() function is currently defined in
mocked_i2c_interface.hpp. This causes linker errors if that header file
is included by multiple .cpp files in the same test executable.

Moved i2c::create() to mocked_i2c_interface.cpp so that it is only
defined once. Created the static library libi2c_dev_mock.a that
contains mocked_i2c_interface.o.

Test executables that need the mock version of i2c::create() should link
with libi2c_dev_mock.a.

Normal executables that need the real version of i2c::create() should
link with libi2c_dev.a as before. This has not changed.
