target/i386: Update EPYC-Genoa for Cache property, perfmon-v2, RAS and SVM feature bits

Found that some of the cache properties are not set correctly for EPYC models.
l1d_cache.no_invd_sharing should not be true.
l1i_cache.no_invd_sharing should not be true.

L2.self_init should be true.
L2.inclusive should be true.

L3.inclusive should not be true.
L3.no_invd_sharing should be true.

Fix these cache properties.

Also add the missing RAS and SVM features bits on AMD EPYC-Genoa model.
The SVM feature bits are used in nested guests.

perfmon-v2     : Allow guests to make use of the PerfMonV2 features.
succor         : Software uncorrectable error containment and recovery capability.
overflow-recov : MCA overflow recovery support.
lbrv           : LBR virtualization
tsc-scale      : MSR based TSC rate control
vmcb-clean     : VMCB clean bits
flushbyasid    : Flush by ASID
pause-filter   : Pause intercept filter
pfthreshold    : PAUSE filter threshold
v-vmsave-vmload: Virtualized VMLOAD and VMSAVE
vgif           : Virtualized GIF
fs-gs-base-ns  : WRMSR to {FS,GS,KERNEL_GS}_BASE is non-serializing

The feature details are available in APM listed below [1].
