docs: Group DTS bindings by type

[nashif]

Summary

In the docs, show bindings by type, right now we only show them by vendors:

https://docs.zephyrproject.org/latest/build/dts/api/bindings.html

Describe the solution you'd like

Using already existing list of types for example dts/bindings/binding-types.txt.

Allow for grouping by type where possible.

Alternatives

NA

Additional Context

Help finding drivers and binding based on category, rather than by vendor
