Downgrade hashing to SHA-1 and other optimizations (#5791) 
This change downgrades hashing algorithm used in caching IR and library bindings to SHA-1. It is sufficient and significantly faster for the purpose of simple checksum we use it for.

Additionally, don't calculate the digest for serialized bytes - if we get the expected object type then we are confident about the integrity.

Don't initialize Jackson's ObjectMapper for every metadata serialization/de-serialization. Initialization is very costly.

Avoid unnecessary conversions between Scala and Java. Those back-and-forth `asScala` and `asJava` are pretty expensive.

Finally fix an SBT warning when generating library cache.

Closes https://github.com/enso-org/enso/issues/5763

# Important Notes
The change cuts roughly 0.8-1s from the overall startup.
This change will certainly lead to invalidation of existing caches. It is advised to simply start with a clean slate.
