Update tianocore branch used with default UEFIPAYLOAD option to
mrchromebox/uefipayload_202107 (July 2021) branch. This branch is
rebased on edk2 upstream commit 12e34cd2f7900578ee83cb01b8f1696a7bb7511b
[OvmfPkg/Bhyve: clean up TPM_ENABLE remnants] vs tag edk2-stable202105.
The main changes are fixes for e820 table parsing and support to disable
"Above 4G decode", which is required to boot distros with bootloaders
that expect to be loaded into RAM below 4G. This fixes booting with
Qubes, ZorinOS, Proxmox, among others.
Additionally, several commits on top of upstream have been consolidated,
reworked, and/or reordered for readability and maintainability.

The GENMASK is defined in multiple files (with various names such as
MASKBIT), which sets certain consecutive bits to 1 and leaves the others
to 0. To avoid duplicate macros, add GENMASK macro to helpers.h.
GENMASK(high, low) sets bits from `high` to `low` (inclusive) to 1. For
example, GENMASK(39, 21) gives us the 64-bit vector 0x000000ffffe00000.
Remove duplicate macro definitions. Also utilize GENMASK for _BF_MASK in
mmio.h.
