Delete D3D9 gpu class. Was fixed-function only, had significant defeciencies around vertex array formats, and is hasn't been updated with respect to parent class changes (won't compile).

-// GrGpu implementation for D3D9 fixed pipeline. 
-// Known needed improvements:
-//      vertex/index buffers need to be better managed:
-//          use no_overwrite and walk down VB/IB until reach end and wrap
-//      take advantage of the redrawHint and don't recopy vertex/idx data
-//      User created vertex buffers must have position Z values 
-//          (required for fixed pipeline) but there is no way to communicate 
-//          this now
-//      We create a temporary sysmem surface for each texture update.
-//      split this out into fixed/shader subclasses (use vdecls for shaders)
