What is changed and how it works?

Issue Number: Close #17767

What's Changed:

IME observes all peer destroy events to timely evict regions. By adding
a new peer, the old and uninitialized peer will be destroyed and IME
must not panic in this situation.

In-memory Engine: Adjust memory settings based on available memory (#17515)

ref #16141

This commit adjusts the following in-memory-engine defaults:

* `capacity`: Now IME uses 10% of the block cache and takes an equal
  amount of memory from the system. This is based on tests showing that
  the IME rarely fills its full capacity.
* `mvcc_amplification_threshold`: Change from 100 to 10 which benefit
  common workloads like TPCc (50 warehouse), saving approximately 20%
  of unified read pool CPU usage.

Also, it addresses two security issues:

* Upgrade hashbrown from yanked 0.15.0 to 0.15.1
