Allow Multiple USB Host Pins (TinyUSB Host)

[arntsonl]

Have you checked the GP2040-CE documentation HERE to confirm this feature doesn't already exist?

Yes

Which problem is this feature request solving?

TinyUSB host allows for multiple USB host pins. I got close in the USB Host Manager, but we should be able to load both keyboard host manager and PS passthrough at the same time.

Describe the solution you would like to see

Add code in to properly initialize tuh_init() and board configs for multiple data + pins.

Describe alternatives you've considered

None

Can you submit a pull request?

I will when I'm done if I code this.

Are you planning on working on this feature yourself?

Yes, most likely.
