Merge branch 'main' into cl/optsize

- Add support for the YUL optimizer details in the standard json input
definition.
- Make optimizer settings optional. They can be omitted and solc will
pick default values ([see here for
reference](https://docs.soliditylang.org/en/latest/using-the-compiler.html#input-description)).

For example allows to use the
[`yul-phaser`](https://github.com/ethereum/solidity/blob/0917604a5ec7cff8bd40a1137f4fcb303fb90527/tools/yulPhaser/README.md?plain=1)
utility. I did a single search with slightly adjusted costs (just made
some educated guess) and after an hour or so this already found an
optimizer sequence
(`OESsShMxeoufcSTvlFxtelTfnfEvicdFxnsvopgCaIeLcnvsTtUrUgdVTUttaeUomccTTTuujsVVvVDvvueUrTjUOmjrrhuuTtj`)
which shrinks the size of the `EndpointV2.sol` from LayerZero by 10%.

 ## Installation
-Please consult [the documentation](https://contracts.polkadot.io/revive_compiler/installation) for installation instructions.
+Building Solidity contracts for PolkaVM requires installing the following two compilers:
+- `resolc`: The revive Solidity compiler YUL frontend and PolkaVM code generator (provided by this repository).
+- `solc`: The [Ethereum Solidity reference compiler](https://github.com/ethereum/solidity/) implemenation.`resolc` uses `solc` during the compilation process, please refer to the [Ethereum Solidity documentation](https://docs.soliditylang.org/en/latest/installing-solidity.html) for installation instructions.
+
+### `resolc` binary releases
+`resolc` is distributed as a standalone binary (with `solc` as the only external dependency). Please download one of our [binary releases](https://github.com/paritytech/revive/releases) for your target platform and mind the platform specific instructions below.

+Note: The `solc` dependency is bundled via NPM packaging and defaults to the latest supported version.
