[BuildRules] Added support to link default lib to the alpaka backends

[smuzaffar]

See cms-sw/cmssw#45285 .
Adding <flags USE_ALPAKA="1"/> OR <flags USE_ALPAKA="Subsystem/Package"/> will add dependency on Subsystem/Package for all the alpaka backends. This is same as using

<use name="1" for="alpaka"/>
OR
<use name="SubSystem/Package" for="alpaka"/>
