loader/nro: Minor changes

gl_shader_decompiler: Simplify GetCommonDeclarations()

vi: Minor changes

hle: Remove unused config_mem and shared_page source files

It's sufficient to use a forward declaration instead of a direct
inclusion here.

Makes the code more uniform, and also braces cases where the body of an
unbraced conditional travels more than one line.

Makes it consistent with the other Apploader constructors, and prevents
implicit conversions.

This isn't used anywhere in the header.

set: Add missing log call in GetAvailableLanguageCodeCount()

It's undefined behavior to memcpy an object that isn't considered
trivially copyable, so put a compile-time check in to make sure this
doesn't occur.

Allows avoiding unnecessary copies of the vector depending on the
calling code.

While we're at it, remove a redundant no-parameter base constructor call

This is just an unused hold-over from citra, so we can get rid of this
to trim off an exposed global, among other things.

This is a holdover from citra that's essentially unused.

Forgot to include this in 22f448b6

string_util: Minor changes

Cleanup

Review fixes

set: Amend return value of GetAvailableLanguageCodes()

This just returns the size of the language code buffer.

The return code should be 32-bit in size.

shader_bytecode: Implement other TEXS masks.

string_util: Get rid of separate resize() in CPToUTF16(), UTF16ToUTF8(), CodeToUTF8() and UTF8ToUTF16()

There's no need to perform the resize separately here, since the
constructor allows presizing the buffer.

Also move the empty string check before the construction of the string
to make the early out more straightforward.

This is equivalent to doing:

push_back(std::string(""));

which is likely not to cause issues, assuming a decent std::string
implementation with small-string optimizations implemented in its
design, however it's still a little unnecessary to copy that buffer
regardless. Instead, we can use emplace_back() to directly construct the
empty string within the std::vector instance, eliminating any possible
overhead from the copy.

We can just use the variant of std::string's replace() function that can
replace an occurrence with N copies of the same character, eliminating
the need to allocate a std::string containing a buffer of spaces.

Kernel/SVC: Perform atomic accesses in SignalProcessWideKey as per the real kernel.

Frontend: Check for more required OpenGL extensions during startup.

 file_util, vfs: Use std::string_view where applicable

gl_shader_decompiler: Remove redundant Subroutine construction in AddSubroutine()

Implement exclusive monitor

externals: Update dynarmic to fc6b73bd

Resolves issues:
* 128-bit exclusive writes on Windows
* Non-updating CNTPCT_EL0

fc6b73 a64_emit_x64: Ensure host has updated ticks in EmitA64GetCNTPCT
888c67 a64_emit_x64: Fix stack misalignment on Windows for 128-bit exclusive writes
352d53 emit_x64_aes: Eliminate extraneous usage of a scratch register in EmitAESInverseMixColumns()
ab7fe7 A64: Implement SADDLV
09bd2b A64: Implement UADDLV
62e86d fp: Use forward declarations where applicable
b3edb7 emit_x64_vector: Append 'v' prefix onto movq in AVX path

We don't need to toss away the Subroutine instance after the find() call
and reconstruct another instance with the same data right after it.
Particularly give Subroutine contains a std::set.

ReplaceFileWithSubdirectory() takes a VirtualFile and a VirtualDir, but
it was being passed a string as one of its arguments. The only reason
this never caused issues is because this template isn't instantiated
anywhere yet.

This corrects an issue before it occurs.

Avoids unnecessary construction of std::string instances where
applicable.

file_util: Remove goto usages from Copy()
