Set correct internalformat info for TexStorageEXT according context type
For ES2 context, EXT_texture_storage enables TexStorageEXT. In the
extension spec, it says for OpenGL ES
"
The TexImage* calls in the TexStorage* pseudocode are modified so that
the <internalformat>, <format> and <type> parameters are taken from the
<format>, <format> and <type> columns (respectively).
"
See https://www.khronos.org/registry/gles/extensions/EXT/EXT_texture_storage.txt.
So, when we set texture level info, internalformat should be adjusted to
format in es2 context.
