346794 maven launch actions enabled for any selection

Maven launch shortcuts were configured to enable for any
IAdaptable for which org.eclipse.m2e.launchable property
evaluated to true. Although not obvious from <launchShortcuts/>
extension point description, properties defined in non-active
bundles are simply ignored. This effectively meant that Maven
launch shortcuts were enabled for any single IAdaptable selection
if m2e.core.ui bundle was not enabled.

Reworked configuration to enable Maven launch shortcuts for any
single selection of IFile with name=pom.xml or IProject with
Maven nature enabled. This slightly different from original logic,
but does not use property testers defined by m2e bundles and should
behave correctly regardless of m2e bundle activation state.

Also removed org.eclipse.m2e.launchable property tester implementation.
It is not used any more and there is no way to use it safely in the
future.
