https://github.com/riscv/riscv-edk2-platforms/commits/riscv-rebased: Same as riscv-virt-gh-actions but rebase on top of upstream master

Rough list of changes

Check out #27 for current draft progress.

• New platform RiscvVirtPkg (Create platform for QEMU's virt target #7)
  • TODO
    • Is it okay to use libraries from ArmVirtPkg (it also uses libraries from OvmfPkg)
• New platform BeagleVPkg (Support BeagleV board #16)
  • TODO
    • Doesn't work still (no console output, nor LED blinking)
• Update to OpenSBI 0.9 (Update to OpenSBI 0.9 (SBI 0.3) #14)
• Use generic OpenSBI platform (they are removing specific ones)
• Build DTB by EDK2 and pass it to OpenSBI when switching to PEI
  • TODO
    • Is it ok to put device tree in FV and skip headers?
• Deduplicate platforms (Deduplicate and split platforms #17)
  • Move generic OpenSbiPlatformLib to Platforms/RISCV/PlatformPkg (possible via DT)
  • Deduplicate PlatformPei
