feat: make filename_impl walker configurable

[sigmaSd]

ref #7715

couple of notes:

• I'm using file_picker config , is that a good idea or should filename have its own config (which will need duplicating FileConfig struct)
• Should I copy all the configs from https://github.com/helix-editor/helix/blob/master/helix-term/src/commands.rs#L2094 I currently only added the options that impact performance

adding another config option might look like this

If BurntSushi/ripgrep#2566 lands, this PR wont be needed

[sigmaSd]

It would be great if this get reviewd, the PR on ripgrep seems to take a while

The motivation is with nucleo space f have no lag but using :o is basically impossible an my old PC, at least with this option I can fix it
