[PATCH 4/4] target/i386: Add EPYC-Venice CPU model

[Ben Cheatham <Benjamin.Cheatham@amd.com>]

Add support for AMD EPYC Zen 6 processors (EPYC-Venice). Add the
following new feature bits on top of the feature bits from the previous
generation EPYC model (Turin):

avx512_fp16		: AVX512 FP16 instructions support
avx_ifma		: AVX512 Integer Fused Mul-Add instructions support
avx_ne_convert	: AVX NE-CONVERT instructions support
avx_vnni_int8	: AVX VNNI INT8 instruction
avx512_bmm		: AVX512 Bit Matrix Multiply instruction
eraps			: Enhanced Return Address Prediction Security support
				  (see also: rapsize)
tsc_adjust		: Time Stamp Counter Adjustment support
cet_ss			: Shadow Stack support
srso_no			: Not susceptible to Speculative Return Stack Overflow
