[rust] xz uncompressor for Firefox Linux nightlies (#14832)

* [rust] Add xz2 dependency

The xz2 crate is already in the dependency tree,
so use it for implementing a xz uncompressor.

* [rust] Add XZ uncompressor

Refactor the BZ uncompressor to be a generic tar uncompressor.
Implement a new XZ uncompressor based on it so selenium-manager
can deal with the new Firefox nightly builds for Linux.
