* am: Initial swkbd implementation
Currently only implements the full screen keyboard, inline keyboard will come later.
* Remove unnecessary logging
* Miscellaneous tidy up
* am: Always pop incoming interactive session data
* am: Add a reminder to implement the full config struct
* am: Check for a max length of zero
We should only limit/truncate text when the max length is set to a non-zero value.
* Add documentation
* am: Return IStorage not available when queue is empty
We should be returning the appropriate error code when the FIFO is empty, rather than just throwing an exception and killing the emulator.
* Fix typo
* Code style changes
* Refactoring HOS folder structure
Refactoring HOS folder structure:
- Added some subfolders when needed (Following structure decided in private).
- Added some `Types` folders when needed.
- Little cleanup here and there.
- Add services placeholders for every HOS services (close#766 and #753).
* Remove Types namespaces
