Merge #1599

1599: Fix Limits for lava/llvmpipe and re-enable and re-work CI r=kvark,groves,wumpf a=cwfitzgerald **Connections** No longer fixes #1551. **Description** This PR has a couple things going on at once. - Fixes limits for llvmpipe, lavapipe, and rpi4. - Added a downlevel limit to express that RPI4 does not allow storage buffers in vertex shaders on GL. - Added a `Limits::downlevel_default()` that takes minimum limits from GLES and adds some more documentation on how to choose limits. - Moved all examples to the new downlevel limits - Reworks CI to re-enable software testing and unify instructions. **Testing** It is Co-authored-by: Connor Fitzgerald <connorwadefitzgerald@gmail.com>
