main: Update for mempool/v2.

This updates the main module to use version 2 of the mempool module.

The following is a summary of changes:

- Update all imports to use mempool/v2
- Update module requirements to include new module and remove no longer
  needed old versions
- Add an override for the v2 module so CI is always builds with the
  latest code
- Update rpcserver getrawmempool to make use of new mempool
  VerboseTxDescs instead of the removed RawMempoolVerbose
- Update rpcserver getrawmempool to properly return the parameter
  provided for the transaction type instead of the type of variable in
  the case an invalid type is provided
- Update rpcserver getrawmempool to return the supported transaction
  types in the error when an invalid type is provided
