Emilio Cobos Álvarez 6fcc03c965 webgl: Make the api return the context limits and use them for validations
This allows keeping the VertexAttrib* calls asynchronous.

Another option would be to do the validation in the apply() function,
but that'd require us passing an unnecessary channel around and add
extra synchronization.

The counterpart of this is that it has to be updated when the context
changes, but that's less problem.
