GL ES 3.0 megapatch (#2061)

* Extend GL ES 3.0 support. Enable CoreProfile capability when using GL ES 3.0. Add WebGL caps.

* Fix contrast adjustment matdef

* Improve GL ->GLES compatibility: Detect if RGB float attachment is supported, implement correct glDrawBuffer shim, add explicit GLES 300 support in all materials

* Allow setReadDrawBuffers in GLES 30+, add DepthTexture capability in GLES 30+

* Make passing boundDrawBufferId to shaders toggleable (default true). Disable in tests

* Revert "Allow setReadDrawBuffers in GLES 30+, add DepthTexture capability in GLES 30+"

This reverts commit d8c7e96d2937bcaa68527cb1b8171a2e11124d35.

* Fix tests

* Set default precision in GLSLCompat only if supported

* Set highp for samplerCube and int. Do not check for GL_FRAGMENT_PRECISION_HIGH as it is not always declared despite the specs.

* Fix GLES formats declaration
