[PATCH v2 1/6] scripts/Kconfig.toolchain: Remove CONFIG_CC_HAS_NO_PROFILE_FN_ATTR

[Nathan Chancellor]

__attribute__((no_profile_instrument_function)) was first supported in
GCC 7 and clang-13, which is higher than both the minimum supported
versions of both compilers. This configuration is always 'y', thus it
can be removed.
