ice: add individual interrupt allocation

Currently interrupt allocations, depending on a feature are distributed
in batches. Also, after allocation there is a series of operations that
distributes per irq settings through that batch of interrupts.

Although driver does not yet support dynamic interrupt allocation, keep
allocated interrupts in a pool and add allocation abstraction logic to
make code more flexible. Keep per interrupt information in the
ice_q_vector structure, which yields ice_vsi::base_vector redundant.
Also, as a result there are a few functions that can be removed.
