feat: add support for preprocessing sources

[grandizzy]

Implements a preprocessor allowing us to skip recompiling tests on non-interface source file changes. See the companion Foundry PR foundry-rs/foundry#10010 for benchmarks and more details.

Supersedes #198:

• uses solar AST instead solang-parser to compute interface representation
• uses solar HIR instead of solc AST to find bytecode dependencies
• handles more edge cases, like deploying with salt/value

Closes #197.

TODO

• use solar HIR (deps to review and include feat(hir): expose hir from parsing context paradigmxyz/solar#210)
• unit tests
• opt-in caching changes
• autodetect mocks
• figure out how to parse when building from different dir
• additional testing (tested with uniswap v4-core and simpler projects)

### Depends on

• merge solar PR (feat(hir): expose hir from parsing context paradigmxyz/solar#210)
• solar release

You can manually load sources with SourceMap::new_dummy_source_file and add them with ParsingContext::add_file

"dummy" isn't right, it's just a way to intern a source file with a String rather than loading from disk

Awesome, that worked, committed in 446a5d8
