Added floating point formats to glCopyTexImage2D
Added floating point formats to validateColorBufferFormat,
which is used by glCopyTexImage2D, since it was a missing
part of the previously added floating point extensions.
From the extension spec:
https://www.khronos.org/registry/gles/extensions/EXT/EXT_color_buffer_half_float.txt
"9. Should CopyTex[Sub]Image be supported for floating-point formats? [...] Yes."
