Revert 253205 "Fix stale reinit in the shader translator."

Caused an assertion error on Windows Debug bots

> Fix stale reinit in the shader translator.
> 
> In some cases we would initialize, free, then re-initialize the
> shader translator within the same initialized memory. The local
> static tracking initialization would get stuck and we would fail
> on subsequent calls. We can fix this by using a non-local static.
> 
> We ran into this problem in some unit tests which use the
> in-process GPU, likely because of the single-process model.
