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`)
