glTexImage2D: Fix confusion between format and internal format

The `format` parameter is similar to `internalFormat` but takes different
values, and especially only `GL_DEPTH_COMPONENT` for depth, without size
specifier.

Cf. https://www.khronos.org/registry/OpenGL-Refpages/es3.0/html/glTexImage2D.xhtml

Fixes a regression from #33278 and another occurrence.
