Lioncash 149a97e396 VideoCommon: Remove unnecessary memset on ShaderUid instances. 
Zero-initialization zeroes out all members and padding bits, so this is
safe to do. While we're at it, also add static assertions that enforce
the necessary requirements of a UID type explicitly within the ShaderUid
class.

This way, we can remove several memset calls around the shader
generation code that makes sure the underlying UID data is zeroed out.
Now our ShaderUid class enforces this for us, so we don't need to care about
it at the usage sites.

Stenzek 1d61041985 ShaderGen: Don't use interface blocks on Vulkan without GS 
Doing so causes the Adreno driver to choke and spew errors about
too many output locations/components, when clearly we're under
the limit.

Stenzek 68cb24172b ShaderGen: Omit some unused varyings when possible 
Removes the clipPos varying unless slow-depth is used, and the
clipDistance varyings if geometry shaders are not used.

Lioncash 50a476c371 Assert: Uppercase assertion macros 
Macros should be all upper-cased. This is also kind of a wart that's
been sticking out for quite a while now (we avoid prefixing
underscores).

Stenzek efb9759862 LightingShaderGen: Always calculate lighting for both color channels 
Cel-damage uses the color from the lighting stage of the vertex pipeline
as texture coordinates, but sets numColorChans to zero.

We now calculate the colors in all cases, but override the color before
writing it from the vertex shader if numColorChans is set to a lower value.

Michael Maltese d10d09ccc1 VideoCommon: rework anamorphic widescreen heuristic 
Some widescreen hacks (see below) properly force anamorphic output, but
don't make the last projection in a frame 16:9, so Dolphin doesn't
display it correctly.

This changes the heuristic code to assume a frame is anamorphic based on
the total number of vertex flushes in 4:3 and 16:9 projections that
frame. It also adds a bit of "aspect ratio inertia" by making it harder
to switch aspect ratios, which takes care of aspect ratio flickering
that some games / widescreen hacks would be susceptible with the new
logic.

I've tested this on SSX Tricky's native anamorphic support, Tom Clancy's
Splinter Cell (it stayed in 4:3 the whole time), and on the following
widescreen hacks for which the heuristic doesn't currently work:

iwubcode a9d08a31a6 Add configurable toggle that rounds vertices to the nearest pixel when 
w=1.  This fixes some games at higher IRs.

Vincent Duvert 8bb459aae5 VideoCommon: Fix GetInterpolationQualifier calls 
Commit 4969415 modified calls to GetInterpolationQualifier, but mistakenly changed the order of some boolean parameters: GetInterpolationQualifier(true, false) was changed to GetInterpolationQualifier(…, false, true).

Should fix #9783.

Our shaders must only depend on the UID, not on any global state.

Jules Blok debaf63fe8 VertexShaderGen: Move the sonic epsilon hack to the vertex shader. 
In the vertex shader we have control over the depth clipping planes,
so we don't have to offset every floating point value and lose accuracy.
