41ce3feb0a test: some tests for push0 
1. `push0_disallowed.yul`: checks if `push0()` is a valid builtin in strict Yul
2. `push0_disallowed.sol`: checks if `push0()` is a valid builtin in inline assembly
3. `push0.sol`: simple semantic test that returns 0
4. `evmone_support.sol`: tests if push0 works properly in evmone
5. Updated some bytecode too large tests to use `shanghai` as version
6. Updated various tests where `push1 0` was hardcoded in different forms / expectations on bytecode
size (`Assembler.cpp`, `GasCosts.cpp`, `SolidityCompiler.cpp`, `SolidityExpressionCompiler.cpp`)

Adds support for the EVM version "Paris". 
Deprecates `block.difficulty` and disallow `difficulty()` in inline assembly for EVM versions >= paris.
The change is due to the renaming introduced by EIP-4399 (see: https://eips.ethereum.org/EIPS/eip-4399).
Introduces `block.prevrandao` in Solidity and `prevrandao()` in inline assembly for EVM versions >= paris.
