Derive project version from git tag

The project version was hardcoded in project(VERSION ...) and in
LSL_LIBRARY_VERSION, so release assets carried a stale version unless
both were bumped by hand.

- cmake/ProjectVersion.cmake: derive MAJOR.MINOR.PATCH (plus the full
  tag incl. pre-release suffix) from the nearest v[0-9]* git tag, with
  the literal as a fallback for git/tag-less builds and a
  LSL_VERSION_OVERRIDE escape hatch.
- CMakeLists.txt: feed PROJECT_VERSION from the tag; use the full tag
  for CPACK_PACKAGE_VERSION so pre-release suffixes survive.
- src/lsl_version.h.in + TargetObjLib.cmake: generate the version
  header so lsl_library_version() tracks the release.
- CI: fetch-depth: 0 on the build-job checkouts so the tag is visible
  to git describe (default shallow clone fetches no tags).
