REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4076

Add support for RISC-V qemu virt machine. Most of the changes are migrated from
edk2-platforms repo and added qemu specific libraries under OvmfPkg.

The series has passed CI tests (https://github.com/tianocore/edk2/pull/3962)

The series can be testes as per instructions @
https://github.com/vlsunil/riscv-uefi-edk2-docs/wiki/RISC-V-Qemu-Virt-support

Changes since V6:
1) Took inspiration from IntelTdx and added all RISC-V qemu related libraries and
modules in OvmfPkg/RiscVVirt instead of directly under OvmfPkg/Library. Hoping for
quicker review since now it shouldn't affect the existing OvmfPkg libraries/modules.
2) Dropped migration of NvVarStoreFormattedLib for now to avoid MdeModulePkg changes.
Currently RISC-V Qemu doesn't support separate variable flash. So, it can be taken
as a separate activity in future when required.
3) Rebased and new CI test request passed

Changes since V5:
1) Avoided editing the existing INF files (as per feedback from Ray Ni). This reduced
several refactor patches.
2) Moved to PEI less design (as per suggestion from Andrei Warkentin)
3) Added PciCpuIO2Dxe driver in OvmfPkg.
4) Removed APRIORI requirement in DSC/FDF infrastructure files. Now they
are very similar to ArmVirtQemu.
5) Addressed Heinrich's feedback.
6) Rebased and added ack tags

Changes since V4:
1) Rebased and added ACKs
2) Dropped few patches related to VirtNorFlashDxe since they are already taken care by Ard.

Changes since V3:
1) Addressed Abner's comments
2) Changed folder name from Ia32_X64 to Ia32X64 as per latest guidelines.
2) Rebased

Changes since V2:
1) Fixed issues detected by CI
2) Added an extra patch to fix up the consumers of NvVarStoreFormattedLib

Changes since V1:
1) Added couple of patches from Ard to optimize the NorFlashDxe in Ovmf.
Note: There will be a separate patch series in future to update existing
consumers of NorFlashDxe driver.
2) Migrated NvVarStoreFormattedLib from EmbeddedPkg to MdeModulePkg
3) Created Null instance of the NorFlashPlatformLib library class
4) Moved NorFlashPlatformLib.h from ArmPlatformPkg
