refactor(kclvm-runner): merge main and refacor kclvm-runner.

  1. Encapsulated method "emit_code" into "lock_ll_file_and_gen_dylib" to
     reduce repetitive code in kclvm-runner/KclvmAssembler.gen_dylibs().
  2. In order to support reuse and simplify the structure of Method "gen_dylibs()",
     encapsulates some operations of cleaning file paths.
  3. Due to issue #79, some test cases are temporarily commented out

  fix #67
