Decompile state system, dYesNoWindow_c and d_profile.cpp

[RootCubed]

Additionally:

• Fixes a few build toolchain issues related to REL building:

  • Don't look up symbol by name in own elf, just check if st_shndx != SHN_UNDEF
  • Don't use FORCEFILES, use EXCLUDEFILES with wiimj2d.elf instead

• Adds -ipa file the build command-line options (needed for matching the state machine code), which meant fixing up some other already decompiled code.

• Slightly changes the profile creation macro; now uses a new enum for the draw order.
