Add a per-thread proc table using thread local storage

Browse Source 
In situations where both dawn_wire and dawn_native are used on separate
threads (Chrome with --single-process or --in-process-gpu), it's
desirable to have a per-thread proc table so that the WebGPU C++ API can
still be used. This eliminates classes of bugs with manual
reference/release errors.

This also changes many of the GetProcs functions to return const
references to the static proc tables known at compile time, instead of a
copy.

Bug: none
