Add support in basetypes for ListValues.ElementsValuePointer

[remyleone]

Module version

github.com/hashicorp/terraform-plugin-framework v1.16.1

Use-cases

When I'm in an update function, I sometimes have to deal with *[]string for a particular attribute in an update request.
It would be helpful to have a way right from types.List to have something ready to be written inside the type.

Attempted Solutions

I can have ad-hoc conversions inside the code of the update but it seems cumbersome to do it for all the different pointer on slice that have to be handled.

Proposal

Add to the types.List a method to have a pointer on this list of element. A little bit similar to what exist for a string: ValueStringPointer().
