gblues 04cefd27d1 Cleanup of Wii U launcher code
== DETAILS

The Wii U main entrypoints were embedded in the frontend driver,
which isn't a great place for them. Also, the `main()` method was
pretty long and monolithic. Now it's (much) less so.

Changes:

- Refactor out the main entrypoints into their own source files
  (`wiiu/main.c` and `wiiu/main.h`)
- Optimize includes in both files, so only the minimum needed to
  compile are included.
- The `main()` method is a lot easier to understand now. It's no longer
a confusing mess of ifdefs.
- There's a small amount of changes in the headers for future work, which
  is switching kpad_driver to be callback-driven. The only change here is
  to import the function that will be used, and define some data types.

Testing:
- Did local builds and confirmed build is successful
- Successfully loaded a core and switched among a few games
