bunnei 34c31db14a GPU: Added RGB565/RGB8 framebuffer support and various cleanups. 
- Centralizes color format encode/decode functions.
- Fixes endianness issues.
- Implements remaining framebuffer formats in the debugger.

Subv c564c21668 GPU: Implemented bits 3 and 1 from the display transfer flags. 
Bit 3 is used to specify a raw copy, where no processing is done to the data, seems to behave exactly as a DMA.
Bit 1 is used to specify whether to convert from a tiled format to a linear format or viceversa.

Yuri Kunde Schlesner a09f71521e GPU: Fix buffer overrun in Display Transfers 
Display transfers with the horizontal downscaling flag were calculating
the wrong output size, causing them to write double the amount of data
intended. It is likely that this was perceived as correct due to a
separate bug in calculating source indices which caused the image to be
padded unless the previous bug was present.

This fixes both issues, correcting flickering issues in 3dscraft,
blargSnes and more (caused by the transfer overwriting the back buffer
which followed) as well as potentially fixing other crashes.

Yuri Kunde Schlesner e29dd76e12 GPU: Correct wrong default framebuffer address for sub-screen. 
It appears this is a mistake, since the sub-screen has no right
framebuffer.

Yuri Kunde Schlesner 98e3274935 GPU: Fire GPU interrupts at the correct places. 
PDC0 and PDC1 are both VBlank interrupts. PDC0 was being treated as a
HBlank interrupt and fired many more times than it should. They now both
fire together at 60 Hz. This puzzlingly *improves* apparent framerate on
many applications.

A few other interrupts were being fired inside the GSP command
processing instead of on the actual GPU register writes, so they were
moved there, which should cover direct writes tho those registers not
going through the GX command queue.

bunnei e9650f1c61 DSP: Signal (faked) interrupt on every frame. 
- Hack to work around games checking that the DSP event has been signaled by a real DSP interrupt.

Tony Wasserka 18a5e888bb GPU: Pseudo-implement horizontal scaling. 
It's not really known how this actually works. Some testing has shown that this probably performs no filtering, and common usage in games suggests it's not actually resizing the image at all.
However, this patch does seem to fix some homebrew showing quasi-duplicated images while still keeping other applications in a working state.

Yuri Kunde Schlesner fec7f6b035 Rename GPU::Regs::FramebufferFormat to PixelFormat 
This name better represents what the enum does, and is less overloaded
in the context. (The whole register the enum is part of is also called
'format'.)

Tony Wasserka 7b6a7d7dfb Pica/GPU: Change hardware registers to use physical addresses rather than virtual ones. 
This cleans up the mess that address reading/writing had become and makes the code a *lot* more sensible.
This adds a physical<->virtual address converter to mem_map.h. For further accuracy, we will want to properly extend this to support a wider range of address regions. For now, this makes simply homebrew applications work in a good manner though.

Tony Wasserka 9c781a6c76 Remove the fancy RegisterSet class introduced in 4c2bff61e. 
While it was some nice and fancy template usage, it ultimately had many practical issues regarding length of involved expressions under regular usage as well as common code completion tools not being able to handle the structures.
Instead, we now use a more conventional approach which is a lot more clean to use.
