* Refactor `validate_block`
This pull request changes the `validate_block` implementation. One of the key changes are that we
free data structures as early as possible. The memory while validating the block is scarce and we
need to give as much as possible to the actual execution of the block. Besides that the pr moves the
validation of the `validation_data` into the `validate_block` implementation completely instead of
using this machinery with putting the data into some global variable that would then be read while
executing the block. There are also some new docs to explain the internals of `validate_block`.

* BlockId removal: refactor: HeaderBackend::header
It changes the arguments of:
- `HeaderBackend::header`,
- `Client::header`
methods from: `BlockId<Block>` to: `Block::Hash`
This PR is part of BlockId::Number refactoring analysis (paritytech/substrate#11292)

* Adds support for returning a custom header from `validate_block`
This adds support for returning a custom header from `validate_block`. Before this, we always
returned the header of the block that was validated (and still do it by default). However, after
this pr it is possible to set a custom header or better custom head data that will be returned
instead from `validate_block`. This can be for example when a chain wants to fork.

* Adds support for checking the timestamp inherent while validating a block
This adds support for checking the timestamp inherent while validating a
block. This will use the relay chain slot number * relay chain slot
duration to calculate a timestamp. This timestamp is used to check the
timestamp in the timestamp inherent.

Currently validation data is shared by using a well known key between
the parachain system pallet and the validate block implementation. This
pr changes this by passing the parachain system directly to the validate
block implementation to make use of it. Besides that, we also store the
validation params in some thread local variable to make it inspectable
by parachain system. This moves the validation of validation data and
validation params to the parachain system pallet directly, instead of
having this hidden inside the validate block implementation.
Fixes: https://github.com/paritytech/cumulus/issues/217
* Move pallets to pallets folder and rename them
* Move genesis file to service
* Rename primitives to primitives-core
* Delete cumulus-runtime
* Move stuff to client folder and rename
