9aef78be4f atirage: Modify write CLOCK_CNTL.
Consider write-only bits: ATI_CLOCK_STROBE can't be read so clear it.
8 bits at Offset 2 is PLL_DATA. If we don't modify PLL_DATA, then insert the current value of PLL_DATA into the value that will be read from ATI_CLOCK_CNTL.

d4fa85688d atirage: Check both offset and size.
When checking if a particular byte of a register is accessed, check both the starting position (offset) and ending position (offset + size) of the bytes being access.

- Add BAR 2 decode. This BAR isn't actually used by Mac OS X, but decode it anyway just in case.
- Support updating of BARs (using change_one_bar method).

214c61669a videoctrl: Add pixel_format.
pixel_format is different than pixel_depth.
pixel_format depends on the GPU. A GPU might have multiple formats for the same depth.
We store this in videoctrl so that we can detect changes in pixel_format like we do for pixel_depth and active_width and active_height.

Cherrypicks a small piece of joevt/dingusppc@117ca1e449

35c86ad6bf Clean up #includes
Result of running IWYU (https://include-what-you-use.org/) and
applying most of the suggestions about unncessary includes and
forward declarations.

Was motivated by observing that <thread> was being included in
ppcopcodes.cpp even though it was unused (found while researching
the use of threads), but seems generally good to help with build
times and correctness.

1f7edfdb3b Make Emscripten build not depend on SDL2 or cubeb
While Emscripten has an SDL compabtility layer, it assumes that the
code is executing in the main browser process (and thus has access to
them DOM). The Infinite Mac project runs emulators in a worker thread
(for better performance) and has a custom API for the display, sound,
input, etc. Similarly, it does not need the cross-platform sound support
from cubeb, there there is a sound API as well.

This commit makes SDL (*_sdl.cpp) and cubeb-based (*_cubeb.cpp) code be
skipped when targeting Emscripten, and instead *_js.cpp files are used
instead (this is the cross-platform convention used by Chromium[^1], and
could be extended for other targets).

For hostevents.cpp and soundserver.cpp the entire file was replaced,
whereas for videoctrl.cpp there was enough shared logic that it was
kept, and the platform-specific bits were moved behind a Display class
that can have per-platform implementations. For cases where we need
additional private fields in the platform-specific classes, we use
a PIMPL pattern.

The *_js.cpp files with implementations are not included in this
commit, since they are closely tied to the Infinite Mac project, and
will live in its fork of DingusPPC.

47d2e235a3 atirage: prevent big-endian accesses outside VRAM.
The simplest solution is to cut the aperture size by the amount
of video RAM installed. This way, accesses to the big-endian
aperture located above the installed VRAM will be catched and
reported by the MMU.
