lib/intel_allocator: Add alloc function which allows passing strategy argument
To use spinners with no-reloc we need to alloc offsets for them
from already opened allocator. As we don't know what strategy
is chosen for open (likely HIGH_TO_LOW for SIMPLE allocator) we
want to overwrite it for spinners (there's expectation they
will reside on low addresses).
Extend allocator API adding intel_allocator_alloc_with_strategy()
to support spinners rewriting.
v2: add change in api_intel_allocator test to compile properly
whole series.
