perf!: Add HasAccount to the AuthKeeper to save protobuf decoding time (

#10022)

* Add HasAccount to the AuthKeeper to save protobuf decoding time

We found in the Osmosis epoch time, the many accesses to GetAccount's proto unmarshalling was a significant slowdown.
This adds a HasAccount method to the AuthKeeper, and fixes one unnecessary spot that it appears within in SendCoins

* Update Spec

* Add Changelog entry

* Fix lint & use speedup in SendCoins

* Update x/auth/keeper/account.go
