Use debug macros even in N64-only code

[cadmic]

After #2296 building N64 ROMs with debug features will be supported, so it would be nice to use e.g. DMA_REQUEST_SYNC instead of DmaMgr_RequestSync everywhere so things are consistent. For the filename, I used whatever filename the existing debug macros used (except for code_n64dd_800AD410.c which we don't know). For unknown file names or line numbers, I used macros UNK_FILE and UNK_LINE which expand to "<unknown>" and 0 respectively.

I think I'd be more comfortable with something like

Suggested change

	_n64ddSegmentRomEnd - _n64ddSegmentRomStart, "../code_n64dd_800AD410.c", 0);
	_n64ddSegmentRomEnd - _n64ddSegmentRomStart, UNK_FILE_NAME, UNK_LINE_NUMBER);

just so it's completely unambiguous to any reader who isn't in the loop that these are fake, in that we can't know what they originally were. These macros could then expand to __FILE__, __LINE__ or just to __FILE__, 0

Alright, I've created UNK_FILE (and turns out UNK_LINE already exists). I don't think the macros should expand to __FILE__ and __LINE__, it seems weird to mix in decomp filenames and line numbers in with the originals. Instead I think it would be better to have versions of the debug macros that put in the real __FILE__ and __LINE__ everywhere if you wanted this for debugging (as @Dragorn421 has suggested before)
