mdbx: поддержка Semantic Versioning.

Было `MAJOR.MINOR.RELEASE.REVISION` Теперь `MAJOR.MINOR.PATCH[.TWEAK][-PRERELEASE][+BUILDMETADATA]` https://semver.org/ - вместо квартета `MAJOR.MINOR.RELEASE.REVISION` триплет c опцинальным четвертым членом `MAJOR.MINOR.PATCH[.TWEAK]` - `TWEAK` не входит в тег git, а формируется автоматически и соответствует кол-ву коммитов после тега git и опускается если 0. - Поле `PRERELEASE` опционально и переносится в версию из тега git. - Поле `BUILDMETADATA` опционально, не входит в тег git, а добавляется во время сборки если задана опцией `MDBX_BUILD_METADATA`.
