shader_decompiler: Asserts for Texture Instructions

* Fix bug where default username value for yuzu_cmd create an userprofile with uninitialize data as username

* Fix format

* Apply code review changes

* Remove nullptr check

kernel/svc: Handle invalid address cases within svcArbitrateLock() and svcArbitrateUnlock()

arm_interface: Remove ARM11-isms from the CPU interface

arm_dynarmic: Correct ExclusiveWrite128()'s operation

Previously the second half of the value being written would overwrite
the first half. Thankfully this wasn't a bug that was being encountered,
as the function is currently unused.

This modifies the CPU interface to more accurately match an
AArch64-supporting CPU as opposed to an ARM11 one. Two of the methods
don't even make sense to keep around for this interface, as Adv Simd is
used, rather than the VFP in the primary execution state. This is
essentially a modernization change that should have occurred from the
get-go.

We already have a ResultCode constant for the case of an invalid
address, so we can just use it instead of re-rolling that ResultCode
type.

The kernel does the equivalent of the following check before proceeding:

if (address + 0x8000000000 < 0x7FFFE00000) {
    return ERR_INVALID_MEMORY_STATE;
}

which is essentially what our IsKernelVirtualAddress() function does. So
we should also be checking for this.

The kernel also checks if the given input addresses are 4-byte aligned,
however our Mutex::TryAcquire() and Mutex::Release() functions already
handle this, so we don't need to add code for this case.

Implemented (Partialy) Shader Header

Optimized Texture Swizzling

service/vi: Replace includes with forward declarations where applicable

kernel/errors: Amend error code for ERR_NOT_FOUND

audio_core/time_stretch: Silence truncation warnings in Process()

gl_shader_decompiler: Get rid of variable shadowing within LEA instructions

services/sm: Amend error code constants

cubeb_sink: Get rid of variable shadowing within CubebSink's constructor

kernel/svc: Handle a few error cases within memory-related functions

cubeb_sink: Correct context name in ListCubebSinkDevices()

Port #4192 from Citra: "svc: change unknown to thread in CreateThread"

Port #4171 from Citra: "Tests: Remove glad test OS X work-around"

Port #4182 from Citra: "Prefix all size_t with std::"

Implement RenderTargetFormat::BGR5A1_UNORM

game_list_p: Take map iterator contents by const reference 

yuzu/util: Antialias game list compatibility pixmaps

Implement ASTC_2D_8X8 

We pass a hint to the QPainter instance that we want anti-aliasing on
the compatibility icons, which prevents the circles from looking fairly
jagged, and actually makes them look circular.

Adds a missing 'i' character that was missing in compatibility.

We don't need to copy the whole struct in this instance, we can just
utilize a reference instead.

Shaders: Implemented multiple-word loads and stores to and from attribute memory.

GPU: Basic implementation of the Kepler Inline Memory engine (p2mf).

This seems to be an optimization performed by nouveau.
