Add the CI steps for building the third_party/NCEPLIBSbufr wheel

[randytpierce]

We need to add CI steps for building the third_party/NCEPLIBSbufr wheel which is a dependency for the prepbufr.
Here are some notes from Ian about getting the python-3.12 working in CI...
As to getting an arbitrary Python version in GitHub actions, it's pretty straightforward. We'd make a new CI definition file, set it up to only run for changes to ./third_party/NCEPLIBS-bufr, and then add something like this to get the desired Python:

jobs:
build:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-python@v5
with:
python-version: "3.12"
- name: "Some build step"
- run: cmake/make/build.sh/etc...
