Bug 1088414. Use a single synchronized texture for d3d11. r=bas,f=jrmuizel

Calling AcquireSync on textures created with
D3D11_RESOURCE_MISC_SHARED_KEYEDMUTEX appears to be really slow, this really
bites us with the number of textures involved when tiling.

I've also tested using ID3D11Query to check when work is completed, this also
appears to be pretty slow.

This instead just uses a single texture with a keyedmutex, and makes sure we
draw to it last and lock it first. It's pretty hacky, but seems to work really
well so far.
