Copilot review overview
🟡 Changes recommended
The F429 HAL has a compile-time argument mismatch, and peripheral sorting does not produce the intended numeric order.

What changed in this PR
Adapts STM32 peripheral enums and incorporates generic GPIO support from #939.
Changes:
- Generates peripheral enums dynamically with reordered subtype indices.
- Generalizes GPIO ports and adds STM32F429 HAL/board support.
- Adds STM32F429 to the blinky example path.

This makes it so that all peripherals always get added, so this should be good for almost any chip. Only thing that needs to be done is potentially add more indexed peripherals. This commit also fixes the peripheral index to work on chips where the peripherals are not coincidentally in order.

This is currently a bit messy as it includes the changes in #939, this will be fixed once that is merged.
[The commits intended to be in] this PR remove remove the constant strings for which peripherals should be included, and change how
base_perihperal_indexworks. This last change could technically breaking, but it was extremely unreliable as it depended on the order the peripherals were specified by embassy. I do not believe any correct usage is affected.
