feat: simplify foyer in-memory cache framework

[MrCroxx]

What's changed and what's your intention?

Please explain IN DETAIL what the changes are in this PR and why they are needed. :D

• Allow "get"/"release"/"entry drop" to acquire read lock or lock-free if the algorithm allows.
• Make most Eviction APIs safe, only acquire unsafe Rust while accessing algorithm managed per-entry state with UnsafeCell.
• Replace the "reinsertion" design with release with real "release last ref" design.
• Rename some APIs.

Checklist

• I have written the necessary rustdoc comments
• I have added the necessary unit tests and integration tests
• I have passed make all (or make fast instead if the old tests are not modified) in my local environment.
