feat: FRAME umbrella crate. (#1337)

### Original PR https://github.com/paritytech/substrate/pull/14137 This PR brings in the first version of the "_`frame` umbrella crate_". This crate is intended to serve two purposes: 1. documentation 2. easier development with frame. Ideally, we want most users to be able to build a frame-based pallet and runtime using just `frame` (plus `scale-codec` and `scale-info`). The crate is not finalized and is not yet intended for external use. Therefore, the version is set to `0.0.1-dev`, this PR is `silent`, and the entire crate is hidden behind the `experimental` flag. The main intention in merging it early on is to be able to iterate on it in the rest of [`developer-hub`](https://github.com/paritytech/polkadot-sdk-docs/) efforts. The public API of the `frame` crate is at the moment as follows: ``` pub mod frame pub use frame::log pub use frame::pallet pub mod frame::arithmetic pub use frame::arithmetic::<<sp_arithmetic::*>> pub use frame::arithmetic::<<sp_arithmetic::traits::*>> pub mod frame::deps pub use frame::deps::codec pub use frame::deps::frame_executive pub use frame::deps::frame_support pub use

https://github.com/paritytech/polkadot-sdk/issues/127 - [ ] have a more intentional version bump, as opposed to the current bi weekly force-major-bump - [ ] revise the internal API of `frame`, especially what goes into the `prelude`s. - [ ] migrate all internal pallets and runtime to use `frame` --------- Co-authored-by: kianenigma <kian@parity.io> Co-authored-by: Kian Paimani
