Ports BCAT to use FSC interface

Huge thanks to lioncash for re-ing this for me.

Returns the data that should be returned by PopLaunchParameter kind=ApplicationSpecific.

Previously we were simply returning the account-preselect structure all times but if passed with a different mode the game expects application-specific data. This also adds a hook for BCAT into this allowing us to send the launch parameter through bcat,

Default enabled

Also displays current events if boxcat is selected.

Takes a title ID and simply deletes all the data for that title ID's bcat. Invokes the respective backend command.

Takes a title ID and passphrase (0x40 byte string) and passes it to the backend.

Variant also supports only updating a single directory. These just both invoke backend commands.

Used to query completion status and events for the current delivery task.

Used to read the contents of files and access their metadata.

Used to list and get directories at the root level.

Used to create subclasses to manage files and directories and to list directories.

Used to access contents of download.

Downloads content from yuzu servers and unpacks it into the temporary directory provided. Fully supports all Backend features except passphrase.

Provides the most abstract simplified functions of BCAT as functions. Also includes a NullBackend class which is just a no-op.

Allows other services to call applets without using LLE.
