Description

This draft PR is a copy of #688, demonstrating a possible workaround to pass unit tests and matrix tests with the correct behavior around the -w flag.

Gcc may be compiled to auto include warnings such as -Wformat. However,
passing in `-w` will suppress the enabled format warnings. The previous
query would not raise an issue, as it saw the `-Wformat` flag etc, even
though if `-w` was present, causing gcc to run with no warnings enabled.

Confirmed that this passes gcc and clang matrix testing.

Both of the following commands:

pwsh scripts/matrix_testing/CreateMatrixTestReport.ps1 -Configuration gcc -Rule -RuleName "A1-1-2"
# and
pwsh scripts/matrix_testing/CreateMatrixTestReport.ps1 -Configuration clang -Rule -RuleName "A1-1-2"

produce the following csv:

"PACKAGE","TEST_PASS","COMPILE_ERROR_OUTPUT","COMPILE_PASS","RULE","QUERY","SUITE","TEST_DIFFERENCE"
"Toolchain","True","","True","A1-1-2","CompilerWarningLevelNotInCompliance","AUTOSAR",""
"Toolchain","True","","True","A1-1-2","CompilerWarningLevelNotInCompliance","AUTOSAR",""
"Toolchain","True","","True","A1-1-2","CompilerWarningLevelNotInCompliance","AUTOSAR",""
"Toolchain","True","","True","A1-1-2","CompilerWarningLevelNotInCompliance","AUTOSAR",""

(note that the four rows correspond to the directories A1-1-2, A1-1-2.1, A1-1-2.2, and A1-1-2.3).

@lcartey What do you think? This seems like technical debt, albeit a working solution.
