Update Balances Pallet to use WeightInfo (#6610)

* Update balance benchmarks

* Update weight functions

* Remove user component

* make componentless

* Add support for `#[extra]` tag on benchmarks

* Update balances completely

* Apply suggestions from code review

Co-authored-by: Alexander Theißen <alex.theissen@me.com>

* Fix some tests

* Maybe fix to test. Need approval from @tomusdrw this is okay

* Make test better

* keep weights conservative

* Update macro for merge master

* Add headers

* Apply suggestions from code review
