logging: switch to lg2

After switching to C++20, it is recommended to use `phosphor::lg2`
to format log, and the correct `CODE_LINE` and `CODE_FUNC` values
can be used in log tracking.

Tested: built ledManager successfully and Unit Test passes.

Before: The file does not exist or is empty
After: The file does not exist or is empty, FILE_PATH = /usr/share/phosphor-led-manager/lamp-test-led-overrides.json

MESSAGE=File does not exist, FILE_PATH = /var/lib/phosphor-led-manager/savedGroups
LOG2_FMTMSG=File does not exist, FILE_PATH = {PATH}
CODE_FILE=../../../../../../fp5280g2-workspace/sources/phosphor-led-manager/serialize.cpp
CODE_LINE=63
CODE_FUNC=void phosphor::led::Serialize::restoreGroups()
