Ryan Houdek 04f1f073c8 InstCountCI: Adds RNG support
Some instructions in the SecondaryGroup need RNG support for testing.

Ryan Houdek ac1d2ec1d9 InstCountCI: Ensure output nasm name doesn't conflict
Pretty sure this is why CI is unhappy. If a test in a different file has
the same name then it is highly likely to conflict when nasm is
generating files and will overwrite and erase, causing CI to break.

Include the incoming json filename as part of the asm keys so it can't
conflict here.

Ryan Houdek cbfea75037 Increase maximum instruction name to 128-bytes
Some long name instructions are going beyond 32-bytes. Obviously not
hurting to encode a few additional bytes.

Ryan Houdek e8e52af2e8 CodeSizeValidation: Adds support for overriding CLZero support
Vixl simulator by default doesn't support this.

Ryan Houdek acc7f2fa8f FEX: Adds instruction count CI
Implements CI for tracking instruction counts for generate blocks of
code when transforming from x86 to ARM64 assembly.

This will end up encompassing every instruction in our instruction
tables similarly to how our assembly tests try to test everything in our
instruction tables.

Incidentally, the data for this CI is generated using our assembly
tests. By enabling disassembly and instruction stats when executing a
suite of instructions, this gives the stats that can be added to a json
file.

The current implementation only implements the SecondGroup table of
instructions because it is a relatively small table and has known
inefficiencies in the instruction implementations. As this gets merged I
will be adding more tables of instructions to additional json files for
testing.

These JSON files will support adjusting CPU features regardless of the
host features so it can test implementations depending on different CPU
features. This will let us test things like one instruction having
different "optimal" implementations depending on if it supports SVE128,
SVE256, SVEI8MM, etc.

This initial instruction auditing is what found the bug in our vector
shift instructions by size of zero. If inspecting the result of the CI
run, you can tell that these instructions still aren't "optimal" because
they are doing loads and stores that can be eliminated.

The "Optimal" in the JSON is purely for human readable and grepping
ability to see what is optimal versus not. Same with the "Comment"
section.

According to my auditing spreadsheet, the total number of instructions
that will end up in these json files will be about 1000, but we will
likely end up with more since there will be edge cases that can be more
optimal depending on arguments.
