Replace libsecp256k1 with secp256k1 (#10798)

Browse Source 
* Replace libsecp256k1 with secp256k1

* Wipe ecdsa secret key from memory on drop

* Some comments for a known issue

* Safer core crypto primitives `from_slice` constructor

Previous version panics if slice lenght is not the expected one.

* Unit test fix

* Enable use of global secp256k1 context

* Better comments for ecdsa `Pair` drop

* Replace `libsecp256k1` with `seco256k1` in `beefy-mmr`

Used to convert ecdsa public key to ETH address

* Replace `libsecp256k1` with `secp256k1` in FRAME `contracts`benchmarks

* Temporary rollback of `beefy-mmr` to libsecp256k1

Check for detected build issues

* Cargo fmt

* Rollback of FRAME `contracts` benchmarks to `libsecp256k1`

* Rollback for unrelated changes

* Typo fix

* Add comments for deprecated `ecdsa_verify` and `secp256k1_ecdsa_recover`
