Merge 2.0.1 backport branch into mainline master (#7842)

* Backport paritytech/substrate#7381

* Bring back genesis storage build in aura/timestamp

To not change spec version, see
paritytech/substrate#7686 (comment)

* Backport paritytech/substrate#7238

* Backport paritytech/substrate#7395

* Bump impl_version

* Fix UI tests and bump trybuild dep

See rust-lang/rust#73996

Backports:
paritytech/substrate#7764
paritytech/substrate#7656

* Partially backport paritytech/substrate#7838

* Release frame-support with a dep compilation fix

* Bump patch level for remaining crates

This is done because at the time of writing cargo-unleash does not fully
support partial workspace publishing and mixes both local and crates.io
versions of the packages, leading to errors in the release check workflow.

* Backport paritytech/substrate#7854

...to fix compilation error when using futures-* v0.3.9.

* Adding Changelog  entry for patch release
