Metal: Compute Shaders (#19)

* check for too bix texture bindings

* implement lod query

* print shader stage name

* always have fragment input

* resolve merge conflicts

* fix: lod query

* fix: casting texture coords

* support non-array memories

* use structure types for buffers

* implement compute pipeline cache

* compute dispatch

* improve error message

* rebind compute state

* bind compute textures

* pass local size as an argument to dispatch

* implement texture buffers

* hack: change vertex index to vertex id

* pass support buffer as an argument to every function

* return at the end of function

* fix: certain missing compute bindings

* implement texture base

* improve texture binding system

* remove useless exception

* move texture handle to texture base

* fix: segfault when using disposed textures
