axes were very sensitive when mapping controls.

input_common: GC Controller save and compare against analog origin state

main: Set async gpu properly after loading per-game setting

main/profile_select: Don't prompt for profile selection when only one is available

kernel/handle_table: Remove usages of the global system instance

registered_cache: Remove previous update/dlc if it exists on install

memory_layout: Remove unused data member

These aren't directly important or commonly used within the process, so
we can move these to the bottom to allow everything else to be more
likely to be within a cache line.

Removes even more usages of the global system instance, trimming away
more dependencies on global variables and making them explicit in the
interface.

This is only used in one place, so we can fold it into the calling code,
eliminating a place for the global system instance to be used.

- This checks for and removes old updates or dlc based on title id. If a content meta nca exists within the registered cache, it will attempt to remove all the ncas associated with the content meta before installing a new update/dlc

common/swap: Make use of std::endian

Allows removing a bunch of defines in favor of a two liner.

maxwell_dma: Match official doc and support pitch->voxel copies

Creates a new function that can be expanded later to fix other settings that are known to cause emulation errors across executables.

configuration: Add settings to enable/disable specific CPU optimizations

filesystem: Set various NAND partition sizes to their defaults

gcadapter: Fix crash if gc configured but adapter not connected

gcadapter: Tidy up compiler warnings

udp: Silence a C++20 deprecation warning

configure_general: Explicitly guard use_multi_core when applying setting

Another error that got pass me and only noticed when I was doing the per-game settings UI rework. This prevents asynchronous GPU emulation from being disabled while multi core is enabled as a result of a poorly put together per-game config.

This is likely an oversight during a rebase. Guards use_multi_core to be only set when the global value is in use. It should not make a difference given the current code base, but makes the code sensible.

cmake: pass libusb include directory

Remnant of an early implementation.

This isn't used, so it can be removed entirely, shrinking the structure
size by 8 bytes.

CMakeLists: Enable usage of C++20 on Linux

This also fixes building on Linux with C++20, so we can enable it across
the board for all OSes that we officially support.

CMakeLists: Correct boost asio disabling define name

Previously the name of the define was missing the BOOST_ prefix.
