* Correctly sets default system language for yuzu-CLI

A user reported that yuzu_cmd runs games in Japanese rather than the correct default of English (like yuzu-qt does correctly), this change fixes that.

* fix clang issue

deleted whitespace

Also adds UI option in Debug > Dump section, with the idea later things to be dumped (i.e. other game data or textures, etc) will use the same group box.

* 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

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

Uses -p (--program) and following string as args.

* 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

Instead of using an unsigned int as a parameter and expecting a user to
always pass in the correct values, we can just convert the enum into an
enum class and use that type as the parameter type instead, which makes
the interface more type safe.

We also get rid of the bookkeeping "NUM_" element in the enum by just
using an unordered map. This function is generally low-frequency in
terms of calls (and I'd hope so, considering otherwise would mean we're
slamming the disk with IO all the time) so I'd consider this acceptable
in this case.
