* Remove `serde` requirement from FRAME macros

Currently there is some implicit requirement on `serde` being present in
the `Cargo.toml` of a pallet when `GenesisConfig` is used. This pr
removes this requirement by using the serde attribute `serde(crate = "..")`.

* build a unique reexport of serde in impl_opaque_keys, by abusing paste doc concatenation

The timestamp inherent type was up to now just a simple `u64`. This
worked, but doesn't give you that much guarantees at compile time about
the type. This pr changes that by converting this type to a unit type
wrapper, similar to what we have done for `Slot`.

This is required for some future pr that touches quite a lot of the
inherents stuff :)

Besides this unit wrapper type, this pr also moves the `OnTimestampSet`
trait to `frame_support::traits`.

Currently we wrap every `GenesisConfig` field in an `Option`, while
we require `Default` being implemented for all pallet genesisconfigs.
Passing `None` also results in the genesis not being initialized, which
is a bug as seen from the perspective of a pallet developer?

This pr changes the fields of the `GenesisConfig` to non `Option` types.

* implement

* make default pre/post_upgrade

* simplify Cargo.toml

* revert removal of outdated/private links

* link in pallet-mmr

That was actually a bad idea by me, because it should essentially be the
same as block.header.

Ty @Kianenigma

* Add logs to proc macro pallet.

* update logs.

* allow dispatch result

* remove custom error message

* format

* add forgotten UI test

* fix test

* fix tests

This pr changes the `ExecuteBlock` trait to return the final header that
results from executing the given block.
