Allows capturing screenshot at the current internal resolution (native for software renderer), but a setting is available to capture it in other resolutions. The screenshot is saved to a single PNG in the current layout.

configuration/config: Use an intermediary variable for accessing players

system_archive: Implement open source NgWord2

 kernel/svc: Correct behavior of svcResetSignal() 

gl_rasterizer: Implement a framebuffer cache

gl_shader_decompiler: Implement TEXS.F16

 system_archive: Use a regular function pointer instead of std::function for the file-scope system archive array

service/ldr: Deduplicate instruction cache clearing code in LoadNro()

Perf: Call shrink_to_fit after page-table vector resizing to actually reduce vector capacity

Call shrink_to_fit after page-table vector resizing to cause crt to actually lower vector capacity. For 36-bit titles saves 800MB of commit.

Avoids typing the same long accessor just to retrieve player attributes.

We've already given the constant to the vector itself, so we don't need
to re-hardcode it in the array.

system_archive: Use a regular function pointer instead of std::function for file-scope system archive array

This allows the array to be constexpr. std::function is also allowed to
allocate memory, which makes its constructor non-trivial, we definitely
don't want to have all of these execute at runtime, taking up time
before the application can actually load.

We don't need to specify all of the ARM interfaces explicitly.

Convert high-frequency LUT arrays from constexpr to static constexpr

While partially correct, this service call allows the retrieved event to
be null, as it also uses the same handle to check if it was referring to
a Process instance. The previous two changes put the necessary machinery
in place to allow for this, so we can simply call those member functions
here and be done with it.

Process instances can be waited upon for state changes. This is also
utilized by svcResetSignal, which will be modified in an upcoming
change. This simply puts all of the WaitObject related machinery in
place.

svcResetSignal relies on the event instance to have already been
signaled before attempting to reset it. If this isn't the case, then an
error code has to be returned.

In some constexpr functions, msvc is building the LUT at runtime
(pushing each element onto the stack) out of an abundance of caution. Moving the
arrays into be file-scoped constexpr's avoids this and turns the functions into
simple look-ups as intended.

file_sys: Implement open source system archives

yuzu/game_list_worker: Minor cleanup and code deduplication

Avoids potentially allocating a std::string instance when it isn't
needed.

file_sys/registered_cache: Eliminate variable shadowing

crypto/key_manager: Remove unused variable in GetTicketblob()

kernel/svc: Implement svcCreateEvent and svcSignalEvent

This function simply does a handle table lookup for a writable event
instance identified by the given handle value. If a writable event
cannot be found for the given handle, then an invalid handle error is
returned. If a writable event is found, then it simply signals the
event, as one would expect.

svcCreateEvent operates by creating both a readable and writable event
and then attempts to add both to the current process' handle table.

If adding either of the events to the handle table fails, then the
relevant error from the handle table is returned.

If adding the readable event after the writable event to the table
fails, then the writable event is removed from the handle table and the
relevant error from the handle table is returned.

Note that since we do not currently test resource limits, we don't check
the resource limit table yet.

loader/{nro, nso}: Remove dependency on the System class

kernel/object: Amend handle types to distinguish between readable and writable events

* Rewrited TEX/TEXS (TEX Scalar).

* Style fixes.

* Styles issues.

 kernel/svc: Implement the resource limit svcGetInfo option

Don't try to route PFIFO methods (0-0x40) to the other engines.

Two kernel object should absolutely never have the same handle ID type.
This can cause incorrect behavior when it comes to retrieving object
types from the handle table. In this case it allows converting a
WritableEvent into a ReadableEvent and vice-versa, which is undefined
behavior, since the object types are not the same.

This also corrects ClearEvent() to check both kernel types like the
kernel itself does.

Another hold-over from Citra.

Allows a process to register the resource limit as part of its handle
table.

This is a leftover from #1792
