riscv64: finalize efibind.h

Browse Source 
There's little reason not to derive the RISCV64 version of efibind.h
from the AARCH64 version, especially as the current version is missing
required macros such as EFI_DRIVER_ENTRY_POINT() which breaks the
compilation of some drivers.

The only major difference we introduce from AARCH64 is to consider
that any toolchain that supports RISCV64 is modern enough to support
<stdint.h>. Also, as we preserve the added definition for BOOLEAN,
we guard it with an ifndef in anticipation of MSVC RISCV64 support.

We validated these changes by confirming that they now allow gnu-efi
to be used to compile a set of UEFI drivers for RISCV64.
