Fill in the spec for most texture functions in WebGL 2

Adds TEXTURE_IMMUTABLE_* enums to GetTexParameter which were previously
missing, and adds a note about TexImage3D being removed. Some parts like
format restrictions still need some work.
Added missing semicolon

As pointed out in #694.

Fix minor issues in float texture extension specs

WEBGL_color_buffer_float had a wrong name for the interface, increasing
confusion between it and EXT_color_buffer_float. Also OES_texture_float
and OES_texture_half_float extensions had broken links.
OES_texture_half_float also incorrectly used OES prefix for
EXT_color_buffer_half_float.

bindAttribLocation with matrix attributes

This test verifies that vectors placed via bindAttribLocation right after matricies will fail if there is insufficient room for the matrix.

Add information on planned backwards incompatibility in WebGL 2

It was decided in the WebGL WG F2F that WebGL 2 will not be entirely
backwards compatible with WebGL 1. In particular, there is agreement
that all extensions are not moving over, and always enabling primitive
restart in WebGL 2 significantly streamlines implementations, so that
could be added to this section of the spec.
