[GPU][TESTS] Fix weightless caching tests (openvinotoolkit#27163)

Currently the tests have weightless caching enabled, but the models
tested contain no constants eligible for weightless caching. This fixes
the situation.

To elaborate - all the models have f32 dtype constants by default. In
these particular models all of the constants which would otherwise be
eligible for weightless caching undergo some precision transformation
which invalidates this eligibilty. The PR changes the dtype of the
constants to prevent that and deletes the models which contain no
constants eligible for weightless caching even after the dtype change.
