Tom Englund f7fcbe32c9 renderer: various fixes towards improving gpu calls robustness (#9188) 
ensure framebuffer textures are detached and deleted, avoid leaving framebuffers bound when not needed

* render: avoid calling glDeleteProgram on no program

its safe to do so but it adds a bunch of unnecessery lines in apitrace
when tracing. if guard it and return early.

* opengl: ensure texture and buffers are unbound

ensure bound buffers are unbound after use, also detach textures from
framebuffer before deleting it otherwise it will become dangling and
essentially leak.
