* Migrate decl_outer_dispatch to a proc macro

* Rename calls.rs to call.rs

* Create new construct_runtime_v2 macro

* Add UI test for importing non-existent call part in construct_runtime

* Emit error when construct_runtime imports a non-existent Config part

* Emit error when construct_runtime imports a non-existent Event part

* Migrate decl_outer_inherent to a proc macro

* Emit error when construct_runtime imports a non-existent Inherent part

* Migrate decl_outer_validate_unsigned to a proc macro

* Emit error when construct_runtime imports a non-existent ValidateUnsigned part

* impl for old macro

* fix line width

* add doc

* hide macroes and use unique counter everywhere

* Remove construct_runtime_v2

* Encapsulate pallet part check macros in a module

* Fix macro definitions in dummy part checker

* Tag ProvideInherent impl with #[pallet::inherent] properly for authorship pallet

* Remove Call part from pallets that do not define it

* Add Call part unit tests

* Remove undefined Call part import from offences pallet

* Add tests for expand_outer_inherent

* Remove Call part from pallets that do not define them

* Remove Call part imports from pallets that do not have it defined

* Remove Call part import of the offences pallet from grandpa pallet mocks

* Update frame/support/test/tests/pallet.rs

Co-authored-by: Guillaume Thiolliere <gui.thiolliere@gmail.com>

* Remove Call part imports for pallets that do not define them

* Move inherent tests to inherent_expand

* Add unit tests for expand_outer_validate_unsigned

* Add newline at the end of file

* fix ui test

* Small prayer to RNGsus for fixing CI

* Remove Call part from construct_runtime for randomness collective flip pallet

* Remove Call part import for randomness collective flip pallet

* Summon Laplace's demon instead of praying to RNGsus

* Update test expectations

* fix ui test and make sure it's flaky

* Revert "fix ui test and make sure it's flaky"

This reverts commit 362b6881389c911ef8d9ef85d71c9463f5694b20.

* Comment out test instead of putting it in conditional compilation

* Update UI test expectations

* Update UI test expectations

* Emit error when construct_runtime imports a non-existent Origin part
