Shader_IR: allow lookup of texture samplers within the shader_ir for instructions that don't provide it

VideoCore: Unify const buffer accessing along engines and provide ConstBufferLocker class to shaders.

Revert "ci: Add build name to archive root folder"

This reverts commit 5e553a6c.

shader_bytecode: Make Matcher constexpr capable

Greatly shrinks the amount of generated code for GetDecodeTable().

Collapses an assembly output of 9000+ lines down to ~3621 with Clang,
and 6513 down to ~2616 with GCC, given it's now allowed to construct all
the entries as a sequence of constant data.

video_core/shader: Resolve instances of variable shadowing

Silences a few -Wshadow warnings.

ci: Add build name to archive root folder

hid/npad: Minor cleanup

shader_ir/memory: Ignore global memory when tracking fails

gl_shader_decompiler/vk_shader_decompiler: Resolve implicit fallthrough cases

Ignore global memory operations instead of invoking undefined behaviour
when constant buffer tracking fails and we are blasting through asserts,
ignore the operation.

In the case of LDG this means filling the destination registers with
zeroes; for STG this means ignore the instruction as a whole.

The default behaviour is still to abort execution on failure.

maxwell_3d: Reduce FlushMMEInlineDraw logging to Trace

core: Fix clang-format errors.

Fix null pointer dereference.

video_core/shader/ast: Minor changes to ASTPrinter

These can also trivially be made const member functions, with the
addition of a few consts.

Given all visiting functions never modify the nodes, we can trivially
make this a const member function.

vk_shader_decompiler: Mark operator() function parameters as const references

This member already has an accessor, so there's no need for it to be
public.

The returned string is simply a substring of our constexpr tabs
string_view, so we can just use a string_view here as well, since the
original string_view is guaranteed to always exist.

Now the function is fully non-allocating.

It's never used outside of this class, so we can narrow its scope down.

This can be confusing, given "ident" is generally used as a shorthand
for "identifier".

Makes a few strings nicer to read and also eliminates a bit of string
churn with operator+.

dmnt_cheat_vm: Correct register Restore and ClearRegs behavior

These parameters aren't actually modified in any way, so they can be
made const references.
