clang-format: re-format for clang-18

clang-format-18 isn't compatible with the clang-format-17 output, so we
need to reformat the code with the latest version. The way clang-18
handles lambda formatting also changed, so we have made changes to the
organization default style format to better handle lambda formatting.

See I5e08687e696dd240402a2780158664b7113def0e for updated style.
See Iea0776aaa7edd483fa395e23de25ebf5a6288f71 for clang-18 enablement.

sensor: Implement sensor "PRIORITY"

This commit introduces the `xyz.openbmc_project.Common.Priority`
interface to define the priority of sensors. If a sensor's priority
attribute is specified, this interface is created with the 'priority'
attribute. However, if the priority attribute is not specified, this
interface is not created.

The `xyz.openbmc_project.Common.Priority` interface is used to indicate
the priority level of fan sensors. It provides information about
primary and secondary RPM sensors for dual rotor fans, allowing for a
more specific description of the sensor's priority.

phosphor-dbus-interfaces commit:
https://gerrit.openbmc.org/c/openbmc/phosphor-dbus-interfaces/+/66779

Tested: Build phosphor-hwmon successfully

sensor: Implement sensor "ASYNC_READ_TIMEOUT"

This change will prevent sensors from blocking all other sensor reads
and D-Bus if they do not report failures quickly enough.

If "ASYNC_READ_TIMEOUT" environment variable is defined in the
sensor's config file for a key_type, the sensor read will be
asynchronous with timeout set in milliseconds.

For example for "sensor1":
ASYNC_READ_TIMEOUT_sensor1="1000" // Timeout will be set to 1 sec

If the read times out, the sensor read will be skipped and the
sensor's functional property will be set to 'false'. Timed out futures
will be placed in a map to prevent their destructor from running and
blocking until the read completes (limitation of std::async).

Tested: This patch has been running downstream for over a year to
solve a slow I2C sensor reads causing IPMI slowdown.

Fixes for when sensor value is a double

The change to the xyz.openbmc_project.Sensor.Value interface that moves
the Value property to a double from an int64_t has merged, which
uncovered some problems in the code that was trying to detect the type
and handle it accordingly.

This does remove support for the Scale property on the Value interface,
as meson CI won't even compile with it since the double version of it is
empty and so the function has unused parameters, which meson doesn't
like.

Support averaging power values

Support new env variables 'AVERAGE_power* = "true"' in hwmon config file.
When this env variable is set, power value is the calculated average value.
Otherwise, power value is from power*_input by default.
The new average of power is calculated since the last time the sensor's
values were changed and read.

average =
(cur_average*cur_average_interval - pre_average*pre_average_interval) /
(cur_average_interval - pre_average_interval)

hwmon config example:
AVERAGE_power2 = "true"
AVERAGE_power3 = "true"
AVERAGE_power4 = "true"

Tested: Set AVERAGE_power* in p0 OCC hwmon conf but not in p1 OCC hwmon conf,
then get power sensor info with restapi to check the values.
1. The values of p0*power are all average values.
2. The values of p1*power are all input values.

Note:
Delete $(CODE_COVERAGE_CPPFLAGS) in AM_CPPFLAGS in test/Makefile.am.
This option will define NDEBUG during configuration, then assert in
code doesn't work.
