Subject: [PATCH] ArmVirtPkg/ArmVirtQemu: enable TPM2 support in the PEI phase

Incorporate the PEI components and the associated library class
resolutions and PCD declarations to enable TPM2 support in the
PEI phase.

This patch ports (parts of) the following OvmfPkg commits to
ArmVirtQemu:
- 6cf1880fb5b6 ("OvmfPkg: add customized Tcg2ConfigPei clone",
                2018-03-09)
- 4672a4892867 ("OvmfPkg: include Tcg2Pei module", 2018-03-09)
- b9130c866dc0 ("OvmfPkg: link Sha384 and Sha512 support into Tcg2Pei
                and Tcg2Dxe", 2018-08-16)
- 5d3ef15da7c3 ("OvmfPkg: link SM3 support into Tcg2Pei and Tcg2Dxe",
                2019-07-19)

gEfiSecurityPkgTokenSpaceGuid.PcdTpm2HashMask defaults to 0x0 so
that the TPM init code adopts the currently active PCR banks as
the ones that are enabled by default.
