This patch mechanically replaces None with std::nullopt where the
compiler would warn if None were deprecated. The intent is to reduce
the amount of manual work required in migrating from Optional to
std::optional.
This is part of an effort to migrate from llvm::Optional to
std::optional:

Runtime call to PointerNullifyDerived or AllocatableInitDerived
should only be generated for derived-type allocation of polymorphic entities.
With unlimited polymorphic entities, it is possible that the type spec is not
a derived-type. Avoid failure in that case.

This patch forces pointer and allocatable polymorphic entities to be
tracked as descriptor. It also enables the pointer assignment between
polymorphic entities. Pointer association between a non-polymorphic
pointer and a polyrmophic target might require some more work as
per 10.2.2.3 point 1.

Fortran standard 7.3.2.3 point 7 mentions that a diassociated
pointer dynamic type is its declared type.
in 9.7.2 note 1, when a NULLIFY statement is applied to a polymorphic pointer,
its dynamic type becomes the same as its declared type.
This patch enforce these standard points by calling the runtime function
`PointerNullifyDerived` with the declared type descriptor.

Lowering of allocate statement for polymoprhic pointers is a bit
different than for allocatables. A call to `PointerNullifyDerived`
runtime function is done instead of `AllocatableInitDerived`.

When allocating a polymorphic entity, its type descriptor can come
from the declared type or can be provided in the allocate statement.
This patch adds lowering for allocate on polymorphic by calling
the `AllocatableInitDerived` runtime function with the correct
type descriptor. Some adaptation are made in the code generation
to accept fir.class where it is appropriate.

It seems the needed functionality was already implemented for host associations,
so turn that code into a function and move it into a (hopefully appropriate)
common location and reuse it.

Polymorphic and unlimited polymorphic entities should be handled by runtime. This patch
update the condition in `genDeallocate` to force polymorphic and unlimited polymorphic entities
to be deallocated through a runtime call and not inlined.

From Fortran 2018 standard 9.7.3.2 point 6:
When a procedure is invoked, any allocated allocatable object that is an actual
argument corresponding to an INTENT (OUT) allocatable dummy argument is
deallocated; any allocated allocatable object that is a subobject of an actual
argument corresponding to an INTENT (OUT) dummy argument is deallocated.
Deallocation is done on the callee side. For BIND(C) procedure, the deallocation
is also done on the caller side.

which correspond to SSA results of an operation, and makes it
