pchickey edited PR #2096 from pch/issue-2053 to main:

This PR implements GuestType for GuestPtr<[T]>, and makes it possible to use witx arrays as members of structs or variants of unions.

The impl GuestType for GuestPtr<[T]> where T: GuestType was straightforward enough to write - its just like impl GuestType for GuestPtr<T>, except we read and write the pointer and length fields rather than just a pointer.

@kubkon did the work to get the lifetimes rendered properly in the code generator, this PR just fixed the missing impl and added a proptest to show that it works.

Closes #2053
Based on and supercedes #2054
