This patch adds more check in SmmIsBufferOutsideSmmValid(), to make sure that
SMM communication buffer is only EfiReservedMemoryType/EfiRuntimeServicesCode/
EfiRuntimeServicesData/EfiACPIMemoryNVS. So that the communication buffer will
not touch any OS memory.
The assumption is that a platform reports valid SMM communication buffer at
EndOfDxe, because EndOfDxe is last hook point that SMM code can call-out to
get memory map information.
A platform MUST finish SMM communication buffer allocation before EndOfDxe.
If a DXE or OS driver need do communication after EndOfDxe, it can either
allocate SMM communication buffer before EndOfDxe and save it, or consume
EDKII_PI_SMM_COMMUNICATION_REGION_TABLE table to get general fixed comm buffer.
This is designed to meet Microsoft WSMT table definition on FIXED_COMM_BUFFERS
requirement.

The runtime test whether the compiler supports arithmetic shift of
negative signed numbers currently relies on undefined behavior in C,
which means that all bets are off regarding whether the condition
that follows passes or fails, regardless of whether the compiler in
fact supports arithmetic shift or not.
Relevant quote from ISO C99 (6.5.7/4)
The result of E1 << E2 is E1 left-shifted E2 bit positions; vacated bits
are filled with zeros. If E1 has an unsigned type, the value of the result
is E1 × 2^E2, reduced modulo one more than the maximum value representable
in the result type. If E1 has a signed type and nonnegative value, and
E1 × 2^E2 is representable in the result type, then that is the resulting
value; otherwise, the behavior is undefined.
For historic purposes, let's keep the test in place (although it is doubtful
we actually need it) but rewrite it in a way that prevents compilers from
this century from doing whacky things with it.
