Fix: InitGoogleTest now consumes and removes the --help flag

[Root-Aamir]

Description

Currently, when --help is passed to a GoogleTest binary, InitGoogleTest sets the internal help flag but does not remove the flag from argv. This prevents downstream argument parsers from knowing that the flag has already been handled.

Changes

• Updated ParseGoogleTestFlagsOnlyImpl in gtest.cc to set remove_flag = true when --help or other unrecognized GTest flags are encountered.
• This ensures argc is decremented and the help flag is removed from the arguments list after initialization.

Verification

Reproduced the issue with a manual test runner.

• Before fix: argc remained 2 after InitGoogleTest when passing --help.
• After fix: argc correctly becomes 1.
