New eviction policies - least recently modified (#14624) 
### Summary

This PR introduces two new maxmemory eviction policies: `volatile-lrm`
and `allkeys-lrm`.
LRM (Least Recently Modified) is similar to LRU but only updates the
timestamp on write operations, not read operations. This makes it useful
for evicting keys that haven't been modified recently, regardless of how
frequently they are read.

### Core Implementation

The LRM implementation reuses the existing LRU infrastructure but with a
key difference in when timestamps are updated:

- **LRU**: Updates timestamp on both read and write operations
- **LRM**: Updates timestamp only on write operations via `updateLRM()`

### Key changes:
Add `keyModified()` to accept an optional `robj *val` parameter and call
`updateLRM()` when a value is provided. Since `keyModified()` serves as
the unified entry point for all key modifications, placing the LRM
update here ensures timestamps are consistently updated across all write
operations
