Eugene Yokota 4265b92aa4 perf: Cache content hash of binary files 
**Problem**
sha256 is currently a bottleneck for no-op compilation.

**Solution**
This adds a local, in-memory cache of sha256 hashes of binary files
using their timestamp and file size.
The size of the digest cache can be configured using localDigestCacheByteSize,
which is set to 1MB by default.
