HLE: Fix sign-compare warnings

Fix warnings and more cleanups

- size and version parameters are unused in the libretro implementation,
  so remove them

Fix implicit fallthrough and other warnings

Fix missing-field-initializer warnings

Used [[fallthrough]]; to mark affected areas. Such keyword should be
available since C++11

Update to core options v2 interface

Flash : Erased memory is FFh-filled

https://akkit.org/info/gbatek.htm#gbacartbackupflashrom

update

- Minor refactoring, some variable name and type changes
- Remove unnecessary checks in clock latch
- Fix stuck in whitescreen after Hudson startup logo
- Fix Gamepak error message at initial load of game without prior rtc
  data available to load
- Save the bare-minimum variable needed for rtc (saves only
  Basetime/lastTime)

HuC3: Refactoring to avoid breaking savestates

Savestates are broken due to the change in savestate struct size for
HuC3. Since save/load function also includes save data for other
non-active mappers, the change in size breaks every savesfiles being
made.

This PR refactors the HuC3 clock data struct to be separate from the
main struct, and then only added to save/load functions when HuC3 mapper
is used. This still breaks previous HuC3 states but other mappers should
now not get affected

Solution:
Savestate/LoadState should only include mapper data of current active
running rom, not all mappers even if they are inactive. This will break
every savefile but it would be better for the long run when changes are
neede to be done.

HuC3 Enable save support and update RTC 

- SRAM support is already available, but the battery-enabled flag was
  not enable for 0xFE (HuC3) rom types.
- Hookup rtc support based on local time. This would allow time to sync
  when starting the game. You need to initially set the time first
though on first bootup (RTC support was based on gambatte sources)
