Pls add more unit tests in kclvm_ast and kclvm_error crate.

Improvement suggestions implemented by lint.rs, due to the lack of symbol table information in LintContext, functions such as check_identifier, check_schema_attr and record_use are implemented in a tricky way, which is part of the symbol table implementation (we can query the variable type and whether the variable has been used. )

[Peefy]

remove samples/a.json

[Peefy]

Important things:

1. move lint.rs and lint_def.rs to the lint module
2. re-org the lint module

• lint.rs
• lint_def.rs
• macros.rs
