feat(molecule): support the latest mol grammar

[homura]

Description

The previous version of @ckb-lumos/molecule does not fully support all molecule syntax, such as comment starting with #, comments in table or struct declaration blocks, import syntax, syntax version, newline breaker \r\n in Windows, and more. This PR refactors the parser to support the latest Molecule syntax.

• fully support the test version syntax of Molecule 0.8
• replaced the parser with Peggy, a successor of peg.js, so the output parser does not require any runtime

Type of change

• New feature (non-breaking change which adds functionality)
