Improve performance `Proc#parameters` method(write in Ruby)
benchmark:
```yml
prelude: |
prc = proc{|x, y=42, *other|}
lam = lambda{|x, y=42, *other|}
benchmark:
proc_no_kwarg: |
prc.parameters
proc_given_kwarg: |
prc.parameters(lambda: false)
lambda_no_kwarg: |
prc.parameters
lambda_given_kwarg: |
prc.parameters(lambda: false)
loop_count: 20000000
```
result:
```bash
