* transactional: Fix some nitpicks

This fixes some nitpicks related to the transactional storage stuff from me. As everything was
merged too fast, here are some nitpicks from me. First, the entire functionality is moved into its
own file to have a clear separation. Secondly I changed the `set_transactional_level` to not take
`Layer` by reference. Besides that I have added some docs etc.

* Add some comment

* Move tests

* 

* introduce hard limit to transactional

* add single layer transactional

* remove single_transactional

* Update mod.rs

* add tests

* maybe fix contracts cc @athei



* fmt

* fix contract logic

* Update frame/contracts/src/exec.rs

* Update exec.rs

* add unchecked and custom errors

* Update lib.rs

* Apply suggestions from code review

* Happy new year

Updates the copyright years and fixes wrong license headers.

* Fix the template

* Split HEADER into HEADER-APACHE & HEADER-GPL

* rename system Config to system Trait.

command used:
```
find frame/ bin/ test-utils/ utils/ -name *.rs -exec sed -i 's/system::Trait>::/system::Config>::/g' {} \;
find frame/ bin/ test-utils/ utils/ -name *.rs -exec sed -i 's/impl frame_system::Trait for /impl frame_system::Config for /g' {} \;
find frame/ bin/ test-utils/ utils/ -name *.rs -exec sed -i 's/impl system::Trait for /impl system::Config for /g' {} \;
```
plus some manual ones especially for frame-support tests and frame-system

* make construct_runtime handle Pallet and Module

pallets can now be implemented on struct named Pallet or Module, both
definition are valid.
This is because next macro will generate only Pallet placeholder.

* introduce pallet attribute macro

currently just with tests, frame_system and other example hasn't been
upgraded

* allow to print some upgrade helper from decl_storage

* Improved error msg, typo.

This revert the changes on construct_runtime. Now construct_runtime is
unchanged and instead pallet macro create a type alias
`type Module<..> = Pallet<..>` to be used by construct_runtime

* refactor with less intricated code

* fix ui test with new image

* fix ui tests

* add minor tests
