vo_opengl: make ES float texture format checks stricter

Browse Source 
Some of these checks became pointless after dropping ES 2.0 support for
extended filtering.

GL_EXT_texture_rg is part of core in ES 3.0, and we already check for
this version, so testing for the extension is redundant.

GL_OES_texture_half_float_linear is also always available, at least as
far as our needs go.

The functionality we need from GL_EXT_color_buffer_half_float is always
available in ES 3.2, and we explicitly check for ES 3.2, so reject this
extension if the ES version is new enough.
