cmake : introduce semantic versioning (#26839)

* cmake : introduce semantic versioning (wip)

This commit introduces semantic versioning to llama.cpp.

* squash! cmake : introduce semantic versioning (wip)

* cmake : update test-cmake README notes [no ci]

* include libmtmd in output so show its semversioned

* ci : add make-release workflow

* ci : fix build number check in build-cmake-pkg.yml

* examples : remove trailing whitespace

* ci : abort if upstream ggml version does not exist

* ci : extract step contents into scripts

* ci : add GGML_NATIVE=OFF to ubuntu job

* examples : remove CI build information from test-cmake [no ci]

This commit removes the nightly/release information that I added
previously to keep this focused only on using building and installing
llama.cpp with cmake and being able to quickly verify changes or
troubleshoot issues.

* ci : merge scripts into single script

* remove -dev-build_number support

This commit removes the incremental build number (versioning) support
that I added. This was incorrect and we should only use the semver for
the version. Releases will be tag a nightly build and package
maintainers/managers that build from source can use the tag and it is
therefor important that the correct version is reported. So a
nightly-build will report the semver without the build number. The build
number and commit as availble via cmake and test-cmake has been updated
to include an example of using them:
```console
$ ./build.sh
[test-cmake] version: 0.1.0, build: 10360 (08c69e381)
...
```
