refactor: move project directory under compiler

Move /packages/dbml-parse/src/project/ to /packages/dbml-parse/src/compiler/project/ to colocate project management with the compiler.

Updates:
- Move project/ directory with Filepath, DbmlProjectLayout, and MemoryProjectLayout
- Update compiler import from @/project to ./project
