SWDEV-430963 - Address MIGraphX failures due to unsafe buffer access usage

Compiler seem to be stricter in compiler staging builds related to
safe buffer programming when compared to other component staging builds.
This seem to result in additional errors when -Werror is enabled
in MIGraphX tests.

Removes all the clang pragmas to ignore several type of warnings in all
the headers and adds a single pragma which ignores all warnings using
#pragma clang diagnostic ignored "-Weverything" in hiprtc builtins.
