Extend SIMDE_DIAGNOSTIC_DISABLE_PSABI to Clang

[robinchrist]

I'm using Clang and getting a lot of warnings, like:

otfftpp/include/otfftpp/detail/otfft_avxdit16.h:1197:17: warning: AVX vector argument of type 'const ymm' (aka 'const simde__m256') without 'avx' enabled changes the ABI [-Wpsabi]
                setpz2(xq+s*0xf, addpz2(s08mjs4c_pw_s2amjs6e, h1_s19mjs5d_pw_s3bmjs7f));

For GCC there seems to be something:

simde/simde/simde-diagnostic.h

Lines 82 to 89 in d62ab5a

	/* GCC emits a lot of "notes" about the ABI being different for things
	* in newer versions of GCC. We don't really care because all our
	* functions are inlined and don't generate ABI. */
	#if HEDLEY_GCC_VERSION_CHECK(7,0,0)
	#define SIMDE_DIAGNOSTIC_DISABLE_PSABI_ _Pragma("GCC diagnostic ignored \"-Wpsabi\"")
	#else
	#define SIMDE_DIAGNOSTIC_DISABLE_PSABI_
	#endif

However not for Clang. Could this perhaps be added?

Hello @robinchrist ; yes, I would accept a pull request that added the equivalent for clang
