Minor cleanup: Remove unused header file and namespace

This commit performs minor by removing an unnecessary
header file: phosphor-logging/log.hpp
and namespace: using namespace phosphor::logging

These cleanup changes have no impact on the functionality.
They enhance code cleanliness, reduce potential confusion,
and promote better code maintenance and readability.

Test:
Created a full build to make sure no errors

Implementing Phosphor-Logging/LG2 logging

This commit introduces changes in the phosphor-debug-collector
repository to implement structured logging using the LG2
framework. The existing log calls in the repository,
have been replaced with LG2 logging, facilitates better
log tracking and troubleshooting by offering improved
detail in JSON object values.

Test:
- Created BMC dump
- Created system dump

Here is a example

faultlog: Initial framework for Fault Log

Fault Log is a new type of dump. For details please see
https://github.com/openbmc/docs/blob/master/designs/hw-fault-monitor.md

This commit enables creation and deletion of fault log entries.

Tested: Created and deleted fault log entries by calling the
corresponding D-Bus methods via bmcweb (added extra code in bmcweb for
testing this). Also forced a fault log directory creation error by
changing the code to specify a nonexistent directory path "/abc/def/"
instead of FAULTLOG_DUMP_PATH, and forced a fault log file open error
by creating a directory (manually using mkdir) with the same name as
the file that the fault log manager tried to open.
