0816f447b7 Make ice40::Arch thread-safe 
We move all non-chip data to be private and guard them with an R/W
mutex.

We then modify all calls that access these fields to lock/shared_lock
the mutex as required.

Profiling the code before and after is an exercise left to the reader
:).

499951cb65 Remove legacy graphics API 
For now we do not optimize the OpenGL renderer against the new decal
API, but this can be done in the future.
