  [libc][NFC] Couple of small warning fixes (#67847)

This patch fixes a couple of warnings when compiling with gcc 13:

* CPP/type_traits_test.cpp: 'apply' overrides a member function but is
not marked 'override'
* UnitTest/LibcTest.cpp:98: control reaches end of non-void function
* MPFRWrapper/MPFRUtils.cpp:75: control reaches end of non-void function
* smoke/FrexpTest.h:92: backslash-newline at end of file
* __support/float_to_string.h:118: comparison of unsigned expression in ‘>= 0’ is always true
* test/src/__support/CPP/bitset_test.cpp:197: comparison of unsigned expression in ‘>= 0’ is always true
