Impl'd IsUserAccountSwitchLocked, SetAudioOutVolume, GetAudioOutVolume & Partial impl of GetAccumulatedSuspendedTickChangedEvent

IPC-100 was changed to InitializeApplicationInfoOld instead of InitializeApplicationInfo. IPC-150 makes an indentical call to IPC-100 however does extra processing. They should not have the same name as it's quite confusing to debug.

Since the Mii database uses UUIDs very similar to the Accounts database, it makes no sense to not share code between them.

Updates function tables based off information from SwitchBrew.

The ProfileData is a 0x80-sized structure that stores various pieces of miscellaneous data for the account.

Changed logging to be "Log before execution", Added more error logging, all services should now log on some level

empty() in this case will always return false, since the returned
container is a std::array. Instead, check if all given users are invalid
before returning the error code.

Needed for Shantae - Half-Genie Hero - Ultimate Edition!

This is just flat data, so it doesn't really need to be in the function
itself. This also allows deduplicating the constant for the backup size
in GetImageSize().

Silences compiler warnings related to truncation. This also introduces a
small helper function to perform the clamping of the image size.

Allows unindenting the other branch's code.

With these, `Nintendo Entertainment System - Nintendo Switch Online` loads

This is only used in a shared_ptr, so we can forward declare it.

We have an overload of WriteBuffer that accepts containers that satisfy
the ContiguousContainer concept, which std::array does, so we only need
to pass in the array itself.

Arranges them in the order the members would be initialized

This is no longer used, so it can be removed.

Added ability to change username & language code in the settings ui. Added IProfile::Get and SET::GetLanguageCode for libnx tests (#851)

Avoids unwanted implicit conversions. Thankfully, given the large amount
of cleanup in past PRs, only this tiny amount is left over to cover.

And make IManagerForApplication::CheckAvailability always return false.
Returning a bogus id from GetAccountId causes games to crash on boot.
We should investigate this with a hwtest and either stub it properly or implement it.

The default username for now is "yuzu".
We should eventually allow the creation of users in the emulator and have the ability to modify their parameters.
