hv: cleanup IA32_PAT emulation code r.w.t. to the refactored guest_msrs[]

Browse Source 
Currently there are two fields in ext_context to emulate IA32_PAT MSR:
- ia32_pat: hold the value of the emulated IA32_PAT MSR
- vmx_ia32_pat: used for load/store IA32_PAT MSR during world switch

This patch moves ext_context->ia32_pat to the common placeholder for
emulated MSRs acrn_vcpu_arch->guest_msrs[].

Also it renames ext_context->vmx_ia32_pat to ext_context->ia32_pat to
retain same naming convention in struct ext_context.
