Add CacheRequest utilities and tests

This CL adds a DAWN_MAKE_CACHE_REQUEST X macro
which helps in building a CacheRequest struct.

A CacheRequest struct may be passed to LoadOrRun
which will generate a CacheKey from the struct and
load a result if there is a cache hit, or it will
call the provided cache miss function to compute a value.

The request struct helps enforce that precisely the
inputs that go into a computation are all also included
inside the CacheKey for that computation.
