perf_stats: Remove unused variable within DoFrameLimiting()

aoc_u: Make use of previously-unused CheckAOCTitleIDMatchesBase() function

maxwell_3d/decoders: Remove unused variables

file_sys: Remove unused variables

logging/backend: Add missing services to the log filters

qt: Add UI to manage emulated user profiles

Prevents bug where old username would remain if the new username was shorter in length.

This hasn't been used since ba8ff096

We can just call the function instead of duplicating the code here. This
also prevents an unused function warning.

We also don't need to take the lambda capture by reference. It's just a
u64 value, so by value is fine here.

Also gets rid of an unused variable.

Just a few overlooked services.

Added break types to svcBreak

* Fixed conflict with nfp

* Few fixups for nfc

* Conflict 2

* Fixed AttachAvailabilityChangeEvent

* Conflict 3

* Fixed byte padding

* Refactored amiibo to not reside in "System"

* Removed remaining references of nfc from system

* used enum for Nfc GetStateOld

* Added missing newline

* Moved file operations to front end

* Conflict 4

* Amiibos now use structs and added mutexes

* Removed amiibo_path

patch_manager: Add support for LayeredFS on DLC RomFS

CMakeLists: Use PROJECT_SOURCE_DIR instead of CMAKE_SOURCE_DIR

common: Remove memory_util.h/.cpp

kernel/process: Make the handle table per-process

This was only ever used by the now-removed memory_util functions. Also,
given we don't plan to support 32-bit architectures, this is just a
leftover from citra at this point.

Everything from here is completely unused and also written with the
notion of supporting 32-bit architecture variants in mind. Given the
Switch itself is on a 64-bit architecture, we won't be supporting 32-bit
architectures. If we need specific allocation functions in the future,
it's likely more worthwhile to new functions for that purpose.

gl_shader_decompiler: Implement VSETP

maxwell_dma: Silence compilation warnings

Implemented Alpha Test using Shader Emulation
