Lower call with polymorphic entities to fir.dispatch operation. This patch only
focus one lowering with simple scalar polymorphic entities. A follow-up patch
will deal with allocatble, pointer and array of polymorphic entities as they
require box manipulation for the passed-object.

This patch updates lowering to produce the correct fir.class types for
various polymorphic and unlimited polymoprhic entities cases. This is only the
lowering. Some TODOs have been added to the CodeGen part to avoid errors since
this part still need to be updated as well.
The fir.class<*> representation for unlimited polymorphic entities mentioned in
the document has been updated to fir.class<none> to avoid useless work in pretty
parse/printer.
This patch is part of the implementation of the poltymorphic
entities.

Follow up of https://reviews.llvm.org/D121488. Ensure lower bounds
are `1` when the related dimension extent is zero. Note that lower
bounds from descriptors are now guaranteed to fulfill this property
after the runtime/codegen patches.
Also fixes explicit shape array extent lowering when instantiating
variables to deal with negative extent cases (issue found while testing
LBOUND edge case). This notably caused allocation crashes when dealing
with automatic arrays with reversed bounds or negative size
specification expression. The standard specifies that the extent of such
arrays is zero. This change has some ripple effect in the current lit
tests.
Add move two helpers as part of this change:
- Add a helper to tell if a fir::ExtendedValue describes an assumed size
array (last dimension extent is unknown to the compiler, both at compile
time and runtime).
- Move and share getIntIfConstant from Character.cpp so that it can be
used elsewhere (NFC).

Add the following utility functions:
- getCharacterLengthType
- createStringLiteral
- locationToFilename
