Split-lock emulation can be re-used for uc-lock. In emulate_splitlock(),
it only work if this vmexit is for #AC trap and guest do not handle
split-lock and HV enable #AC for splitlock.
Add another condition to let emulate_splitlock() also work for #GP trap
and guest do not handle uc-lock and HV enable #GP for uc-lock.

When ACRN uses decode_instruction to emulate split-lock/uc-lock
instruction, It is actually a try-decode to see if it is XCHG.
If the instruction is XCHG instruction, ACRN must emulate it
(inject #PF if it is triggered) with peer VCPUs paused, and advance
the guest IP. If the instruction is a LOCK prefixed instruction
with accessing the UC memory, ACRN Halted the peer VCPUs, and
advance the IP to skip the LOCK prefix, and then let the VCPU
Executes one instruction by enabling IRQ Windows vm-exit. For
other cases, ACRN injects the exception back to VCPU without
emulating it.
So change the API to decode_instruction(vcpu, bool full_decode),
when full_decode is true, the API does same thing as before. When
full_decode is false, the different is if decode_instruction() meet unknown
instruction, will keep return = -1 and do not inject #UD. We can use
this to distinguish that an #UD has been skipped, and need inject #AC/#GP back.

Guest may not use INVEPT instruction after enabling any of bits 2:0 from
0 to 1 of a present EPT entry, then the shadow EPT entry has no chance
to sync guest EPT entry. According to the SDM,
"""
Software may use the INVEPT instruction after modifying a present EPT
paging-structure entry (see Section 28.2.2) to change any of the
privilege bits 2:0 from 0 to 1.1 Failure to do so may cause an EPT
violation that would not otherwise occur. Because an EPT violation
invalidates any mappings that would be used by the access that caused
the EPT violation (see Section 28.3.3.1), an EPT violation will not
recur if the original access is performed again, even if the INVEPT
instruction is not executed.
