Per discussion in the WebGL working group, shaderSource no longer
generates INVALID_VALUE for sources containing characters outside the
ESSL character set. Compilation and/or linking is still specified to
fail when illegal constructs are used.
With this change, https://github.com/KhronosGroup/WebGL/pull/3206
passes with the passthrough command decoder.
Revise WebGL compatibility tests to follow the new rules.
