Instead of waiting and infinite time, abort the TPM PPI request after
3 minutes. This allow to boot headless platforms where no keyboard is
attached or the user didn't made it in time.

Put the PPI configuration retriveal into an own library.
That will allow to reuse the code in the UefipayloadPkg, where the
firmware provides the ACPI tables, like QEMU does on OvmfPkg.
However one major difference is that the PPI interface in UefiPayloadPkg
is not backed by a MMIO device, but resides in DRAM and is shared with ACPI code.
Add an additional parameter to provide the location of the PPI and
test if the memory region has the correct attributes.

Cloned "SecurityPkg/Library/DxeTcg2PhysicalPresenceLib" and:
- removed all the functions that are unreachable from
Tcg2PhysicalPresenceLibProcessRequest() [called from platform BDS],
or SubmitRequestToPreOSFunction() and
ReturnOperationResponseToOsFunction() [called from Tcg2Dxe].
- replaced everything that's related to the
TCG2_PHYSICAL_PRESENCE*_VARIABLE variables, with direct access to
the QEMU structures.
This commit is based on initial experimental work from Stefan Berger.
In particular, he wrote most of QEMU PPI support, and designed the
qemu/firmware interaction. Initially, Stefan tried to reuse the
existing SecurityPkg code, but we eventually decided to get rid of the
variables and simplify the ovmf/qemu version.
