texture: rename texobj flush code as gl specific

This renames the set_filters and set_wrap_mode_parameters texture
virtual functions to gl_flush_legacy_texobj_filters and
gl_flush_legacy_texobj_wrap_modes respectively to clarify that they are
opengl driver specific and that they are only used to support the legacy
opengl apis for setting filters and wrap modes where the state is
associated with texture objects instead of being associated with sampler
objects.

This part of an effort to clearly delimit our abstraction over opengl so
that we can start to consider non-opengl backends for Cogl.
