[Feature]: Patch release improvement to x/slashing begin block logic

[ValarDragon]

Summary

BeginBlock logic for slashing takes 2-3% of sync time right now, even in v24.

We can in a patch release speed this up by:

• Making signedblocks window not call GetParams. Use passed in params
• Making a single logger call, not one per validator
• Cache MinSignedPerWindowInt

That would speedup sync speed by ~.8%.

We may also be able to patch release improve GetMissedBlockBitMapChunk by skipping getting a chunk from state if a validator has 100% uptime and signed the block.
