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:

Some named value operands are not used yet (TODOs). Some compilers
complain about it. Remove names of unused parameters.

Lower not, negate, and complex component to HLFIR.
Parentheses is the only remaining operation, but needs some
care/thinking to properly deal with character/derived variables.

evaluate::SetLength is the last intrinsic binary operation
that needs to be lowered to HLFIR. It will require an hlfir.set_length
op or hlfir.as_expr to convert the result to an expression. Add a TODO
for now.

Update BinaryOp<T>::gen so that const T& is threaded and some
operation knowledge that is not encoded by the type T or the arguments
can be used. For Extremum, it is the order (Greater or Lesser) that is
required, but this will also be required for evaluate::Relational.

Use recently added hlfir.associate/hlfir.end_associate to deal
with the cases where the actual argument is an expression.

Also add support for fir.boxchar in HLFIRTools so that character
designator with none constant lengths can be processed/converted to
fir::ExtendedValue.

This reflects the fact that Attributes will not always be visible when
looking at an HLFIR variable. The EntityWithAttributes class is used
to denote in the compiler code that the value at hand has visible
attributes. It is intended to be used in lowering so that the code
can query about operands attributes when generating code.

Use the utility to lower Constant<T> that was split from current lowering
in https://reviews.llvm.org/D136955.
The difference in HLFIR is the addition of a fir.declare on constant
outlined in memory so that all the information about them is available.
Lowering to HLFIR is enabled in Brideg::genExprValue to allow testing
of scalar constant lowering.

This patch adds the kernel to lower evaluate::Expr to HLFIR to a
hlfir::FortranEntity (a single mlir::Value that can be interpreted as
a Fortran variable or the value of a Fortram expression).
It implements lowering of simple name designators ("x") and starts
adding a translation layer in AbstractConverter::genExprBox and
AbstractConverter::genExprAddr so that the new expression lowering
can be used without any changes for now in the current statement and
construct lowering.
