The prototypes of EbcInterpret() and ExecuteEbcImageEntryPoint() are
private to the AARCH64 implementation of EbcDxe, so we can shuffle
the arguments around a bit and make the assembler thunking glue a lot
simpler.
For ExecuteEbcImageEntryPoint(), this involves passing the EntryPoint
argument as the third parameter, rather than the first, which allows
us to do a tail call. For EbcInterpret(), instead of copying each
argument beyond #8 from one native stack frame to the next (before
another copy is made into the VM stack), pass a pointer to the
argument stack.

Instead of pessimistically copying at least 64 bytes from the VM stack
to the native stack, and popping off the register arguments again
before doing the native call, try to avoid touching the stack completely
if the VM stack frame is <= 64 bytes. Also, if the stack frame does exceed
64 bytes, there is no need to copy the first 64 bytes, since we are passing
those in registers anyway.

The thunk generation is needlessly complex, given that it attempts to
deal with variable length instructions, which don't exist on AArch64.
So replace it with a simple template coded in assembler, with a matching
struct definition in C. That way, we can create and manipulate the thunks
easily without looping over the instructions looking for 'magic' numbers.
Also, use x16 rather than x9, since it is the architectural register to
use for thunks/veneers.

even if the native function's arguments are less than 4.
From MSDN x64 Software Conventions, Overview of x64 Calling Conventions:
“The caller is responsible for allocating space for parameters to the
callee, and must always allocate sufficient space for the 4 register
parameters, even if the callee doesn’t have that many parameters.
This aids in the simplicity of supporting C unprototyped functions,
and vararg C/C++ functions.”

a. Addresses an information gap between INF files and the UEFI Distribution Packaging Specification XML schema
b. There will be an associated update to UPT in BaseTools to consume MODULE_UNI_FILE and associated UNI file during UDP creation that performs the INF -> XML conversion.

3. Add Module Extra UNI file that provides the localized Name of a module.
a. [UserExtensions.TianoCore."ExtraFiles"] provides an easy method for a module to specify extra files not listed in [Sources] or [Binaries] sections to be added to a UDP without having to list the files in the UPT package information data file.
b. There will be an associated update to UPT in BaseTools to package up files listed in [UserExtensions.TianoCore."ExtraFiles"] during UDP creation.
c. UNI file contains localized name of a module to go along with the localized Abstract and Description from the MODULE_UNI_FILE.
