The only caveat here is that gfxVars are not atomic, but multiple threads can
query DWM status. To solve this, changes to the var are mirrored into an atomic
and that is read instead.
DWM status changes are indicated by Windows via a window message. We use that
window message to cause the update to propagate

We have encountered issues when rolling out WebRender because the
configuration logic is quite complicated. It would serve us well to have
it in a form that we can easily test. This patch does said refactor, as
well as adds an initial set of tests.

Add a gecko pref "gfx.webrender.use-optimized-shaders". If enabled,
then when attempting to compile a webrender shader first look for the
optimized source. If the optimized source is not present, emit a
warning and fall back to the unoptimized source.
Use the optimized source by default in wrench, and add the flag
"--use-unoptimized-shaders" to override this.

We need a way to switch it on and off to compare the performance and power usage of various test cases.
The new pref is "webrender.enable-multithreading" and does not require a restart.

This patch only allows sacrificing subpixel anti-aliasing when the
screen size is larger than WUXGA, and when the force disable pref is not
set. In the future, we may also add disable this for high end GPUs.
This also consolidates the WebRender debug flags to use the same
signaling infrastructure to avoid needing to store the debug flag state
and check on each transaction. Instead it now applies the debug flag
updates when the gfxVar changes.

When Windows version is mort than 1903 and GPU is intel GPU, it could cause flickering with DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL. See Bug 1556634. As a short term workaround, use DXGI_ALPHA_MODE_PREMULTIPLIED instead of DXGI_ALPHA_MODE_IGNORE at SwapChain.

Investigation showed that on this platform the texture unit state becomes
corrupted whenever we set the non-identity swizzling (getting garbage from textureSize()).
Given no easy workaround, we disable swizzling for this GPU family on Mac, for now.

When double buffering is enable with compositor, DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL is used without DirectComposition. There are some devices that swap chain with DXGI_SWAP_EFFECT_FLIP_SEQUENTIAL does not work well. In this case, device reset happens very often. To avoid the situation, the double buffering needs to be disabled when device reset happens.

StaticPrefs doesn't support nsCString type and the changes required to support this would be rather big. Seeing that there was only a single gfxPrefs using this, and this is a "Once" pref ; we move it to gfxVars instead.

This was done automatically replacing:

s/ Move(/ std::move(/
s/(Move(/(std::move(/
Removing the 'using mozilla::Move;' lines.
And then with a few manual fixups, see the bug for the split series..
