Implement flushing in the rasterizer cache

svc: Clarify enum values for AddressSpaceBaseAddr and AddressSpaceSize in svcGetInfo()

Implement Arrays on Tex Instruction

savedata_factory: Add DeviceSaveData and fix TemporaryStorage

- This will be used as a catch-all for slow-but-accurate GPU emulation paths.

- This does not really have anything to do with OpenGL.

- These cannot be used within the cache, as they change cache state.

content_archive/patch_manager: Lower log levels to eliminate some unnecessary logs

* Implement VI ConvertScalingMode

* Fixed push enum

* Scale mode now uses Nintendo scale mode as an enum as well

core: Convert shared_ptr instances into unique_ptr instances where applicable for System and Cpu

file_sys/registered_cache: Use unique_ptr and regular pointers instead of shared_ptrs where applicable

Port citra-emu/citra#4327: "travis: Ignore binary files when checking for trailing whitespace"

Required for TemporaryStorage saves (in addition to SaveDataType)

Uses the same path as SaveData except with UID 0. Adds a warning if UID is not 0.

file_sys/registered_cache: Use unique_ptr and regular pointers instead of shared_ptrs where applicable

The data retrieved in these cases are ultimately chiefly owned by either
the RegisteredCache instance itself, or the filesystem factories. Both
these should live throughout the use of their contained data. If they
don't, it should be considered an interface/design issue, and using
shared_ptr instances here would mask that, as the data would always be
prolonged after the main owner's lifetime ended.

This makes the lifetime of the data explicit and makes it harder to
accidentally create cyclic references. It also makes the interface
slightly more flexible than the previous API, as a shared_ptr can be
created from a unique_ptr, but not the other way around, so this allows
for that use-case if it ever becomes necessary in some form.

web_service: Make linkage of web_service-related externals and the library private

yuzu/main: Apply the [[maybe_unused]] attribute to the parameter of SetDiscordEnabled

file_sys/control_metadata: Get rid of magic constants

These are just the size of the data being passed in, so we can specify
that via the size() member function.

aoc: Fix various bugs in current AOC implementation

nro/nso: Minor error handling changes

crypto: Various crypto fixes for quickstart guide

If a malformed NSO is attempted to be loaded, we shouldn't continue
onwards. We should be reporting an error and bailing out.

video_core: Minor style changes

Control Code 0xf means to unconditionally execute the instruction. This
value is passed to most BRA, EXIT and SYNC instructions (among others)
but this may not always be the case.
