8757e0aa11 feat: add support for push0 in libevmasm 
See https://eips.ethereum.org/EIPS/eip-3855

Note: `push0` costs 2 gas, i.e., `Tier::Base` unlike other pushes.

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.

- SemanticTests accepts fully qualified library name and also unqualifed library name when
the library is defined in the same file for convenience.
