debug_pad: Avoid loading input for nonexistent buttons (Home and Screenshot)

Prevents memory exceptions when the debug pad is enabled.

maxwell_3d: Implement alternate blend equations.

audout_u: Add support for multiple IAudioOut streams.

macro_interpreter: Implement AddWithCarry and SubtractWithBorrow.

Implemented Fast Layered Copy

common: Remove bit_set.h

kernel/handle_table: Minor changes

This is an analog of BitSet from Dolphin that was introduced to allow
iterating over a set of bits. Given it's currently unused, and given
that std::bitset exists, we can remove this. If it's ever needed in the
future it can be brought back.

These don't depend on class state, and are effectively implementation
details, so they can go into the cpp file .

The previous handle table size is a holdover from Citra. The actual
handle table construct on Horizon only allows for a maximum of 1024
entries.

We don't need to potentially inline the teardown logic of all of the
handle instances.

Use default values for unknown framebuffer pixel format

gl_shader_decompiler: Use UNIMPLEMENTED when applicable

am/applets: Minor cleanup

gl_shader_decompiler: Remove UNREACHABLE when setting RZ

common/math_util: Minor cleanup

common: Remove depencency on xbyak

Xbyak is currently entirely unused. Rather than carting it along, remove
it and get rid of a dependency. If it's ever needed in the future, then
it can be re-added (and likely be more up to date at that point in
time).

Gets rid of the need to use typename to access the ::type alias.

Allows objects that contain rectangle instances to be constexpr
constructible as well.

const/constexpr variables have internal linkage by default.

This hasn't been used since the project started, so we may as well get
rid of it to keep it from bit rotting.

maxwell_3d: Initialize rasterizer color mask registers as enabled.

am: Correct build failure

- Fixes rendering regression with Sonic Mania.

The interface for shared memory was changed, but another commit was
merged that relied on the (previously public) internals of SharedMemory.

This amends that discrepancy.

kernel/shared_memory: Make data members private, plus minor interface changes

ldr: Clean up error codes

kernel/process: Move <random> include to the cpp file

common/assert: Make the UNIMPLEMENTED macro properly assert

file_sys/card_image: Provide named members for the GamecardInfo struct

Fills out the struct according to information provided by SwitchBrew

Currently, there's no way to specify if an assertion should
conditionally occur due to unimplemented behavior. This is useful when
something is only partially implemented (e.g. due to ongoing RE work).
In particular, this would be useful within the graphics code.

The rationale behind this is it allows a dev to disable unimplemented
feature assertions (which can occur in an unrelated work area), while
still enabling regular assertions, which act as behavior guards for
conditions or states which must not occur. Previously, the only way a
dev could temporarily disable asserts, was to disable the regular
assertion macros, which has the downside of also disabling, well, the
regular assertions which hold more sanitizing value, as opposed to
unimplemented feature assertions.
