feat(forge): implement forge check for fast syntax and semantic analysis

[wellnana]

closes #11965

Adds a new forge check subcommand that performs parsing, lowering, and semantic analysis without codegen and optimizer steps.

Usage:

1. Check entire project: forge check
2. Check specific files: forge check src/MyContract.sol
3. Watch mode for continuous checking: forge check --watch

Hi, as mentioned in the original issue, this is currently blocked. Merging and shipping this command in its current state would not make a lot of sense. For that reason I've marked this as a draft.
