feat(volo-build): add with_comments option for codegen builder

[Ggiggle]

Motivation

The comments in user idl, will be checked by rust compiler, when these comments are generated in rust file.

Solution

We add a option for the control of comments, so when you need comments codegen, you should make sure that your comments is compatible with rust format.

And we support the yml field with_comments, which is the config for each entry.
