Adjust SwiftShader WebGL expectations

Remove conformance/textures/misc/compressed-tex-image.html expectation

Skip unsupported extensions expectations on SwiftShader
Also skip unsupported extensions expectations on other platforms,
to speed up test execution.

This takes a different approach to handling conflicting expectations.
SwiftShader expectations are duplicated for linux, mac, win.
Other expectations are simplified to their original version.
