target/i386: Update EPYC-Milan CPU model for Cache property, RAS, SVM feature bits

target/i386: Update EPYC-Milan CPU model for Cache property, RAS, 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-Milan model.
The SVM feature bits are used in nested guests.

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
