https://github.com/void-linux/void-packages/pull/31687

Update libgdal and proj and rebuild against them
<!-- Mark items with [x] where applicable -->

#### General
- [ ] This is a new package and it conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements) --> Contains 3 related new packages, see below.

#### Have the results of the proposed changes been tested?
- [x] I use the packages affected by the proposed changes on a regular basis and confirm this PR works for me
    **I use PostGIS regularly and this works for me.**
- [x] I generally don't use the affected packages but briefly tested this PR
    **I generally don't use the other packages which have to be rebuilt against proj and/or gdal, but I did test all of them briefly**.

#### Motivation

- These updates and additions are in preparation for adding QGIS.
- SpatiaLite is a lightweight, versatile spatial extension to SQLite. Libkml is needed to provide KML support to SpatiaLite, and librttopo is required to create genuine SpatiaLite-5 DB layout, as well as to pass SpatiaLite tests.

If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.
