[GLUtils] Pass the correct format into glTexImage2D and glTexSubImage2D.

Previously, the format and internal format are the same, however, per
https://www.khronos.org/registry/OpenGL-Refpages/es3.1/html/glTexImage2D.xhtml,
this is no longer the case, thus we need to convert to proper format when we
have the sized format.
