feat: Implement SyncLruCache (#5259)

This is just a proof of concept.

Implement a cache that works from a "&" context.

- get_from_cache_or_insert - gets a value or inserts a computed value
- get_from_cache - tries to get value

TODO:
- [x] rename methods
- [x] add new methods
- [x] benchmarks
- [x] comments
- [x] add more tests.
- [x] one example of replacing real code
- [x] implement example with `lru` (done in another PR)
- [x] Use `once_cell` instead of `lazy_static!` (done in another PR).
