OvmfPkg: Add INVD case in #VE handler

According to the Intel GHCI specification document section 2.4.1, the
goal for instructions that do not have a corresponding TDCALL is for the
handler to treat the instruction as a NOP.

INVD does not have a corresponding TDCALL. This patch makes the #VE
handler treat INVD as a NOP.
