Most tests were only being run for layout-2013, not for layout-2020.
This wasn't great since layout-2020 is now the default.
So this patch unifies the lists of included tests for both layouts.
For layout-2013 this implies adding css/css-content/, css/css-logical/
and css/css-masking/clip/.
For layout-2020 this implies adding several additional css tests, and
also tests like dom/, js/, html/, etc.
Add support for WebGL2 TexImage2D
Adds initial support for one of the WebGL2 `TexImage2D` call.
I've enabled the `tests/wpt/webgl/tests/deqp/` tests.

The implementation was already in place for OpenGL ES.
My approach with this patch is to add support for WebGL2 by
sharing the implementation between the WebGL2 and GLES.
It seems the WPT test runner/updater has some troubles picking up
successful test results, so I've regenerated the `ini` files manually
for the WebGL2 tests.
