Embed the google cache dependency in the bundle

Guava is known as a bit "problematic" dependency, as lemminx only uses
guava-cache, this can be embedded in the bundle and be made embedded
package.

This changes the used felix-bundle to bnd-maven-plugin with the
conditionalpackage to include the caching api in the generated bundle
