Solidity 0.8.31 Adds Fusaka Features and ARM Builds

Solidity Compiler v0.8.31 supports Fusaka upgrade features and adds ARM Linux builds. Deprecations warn for ABI coder v1, virtual modifiers, send/transfer, and contract type comparisons ahead of v0.9.0. New Yul builtin clz(x) counts leading zeros. Default EVM version is osaka. Boost, GCC, and Clang minimum versions raised. Thanks to contributors including Afonso Souza, Patrick Collins, and others.
