[Test] Replace 0.0.0 version with "detached" property on ElasticsearchDistibution (elastic#134584)

Introduce a new `detached` property to indicate if the version is a custom build
not tied to any release. This was previously handled by specifying
version as 0.0.0, but caused problems when comparing versions (e.g., to
decide on configuration).

(cherry picked from commit 664a604)
