feat(sequencer): transfer fees to block proposer instead of burning (#…

…690)

## Summary
accumulate block fees during tx execution and transfer them to the block
proposer in `end_block`.

## Background
we don't want to burn tx fees especially not if they are IBC assets.

## Changes
- implement `get_block_fees`, `get_and_increase_block_fees`, and
`clear_block_fees` which get, increase, and clear the block fees
respectively
- during action execution where there is fee payment (transfer and
sequencer), update the current block fees state.
- in `begin_block` store the proposer address (needed b/c `end_block`
doesn't receive it, this can be removed when we move to comet 0.38)
- in `end_block` transfer the fees to the proposer and clear the cached
address

## Testing
unit test

## Breaking Changelist
changes the state by not burning tokens.
