Reapply "[mlir] Mark `isa/dyn_cast/cast/...` member functions depreca… (#90406)

…ted. (#89998)" (#90250)

This partially reverts commit 7aedd7dc754c74a49fe84ed2640e269c25414087.

This change removes calls to the deprecated member functions. It does
not mark the functions deprecated yet and does not disable the
deprecation warning in TypeSwitch. This seems to cause problems with
MSVC.

[flang] Remove 'using namespace mlir;` from header files

Currently, CGOps.h and FIROps.h contain `using namespace mlir;`. Every
file that includes one of these header files (directly and transitively)
will have the MLIR namespace enabled. With name-clashes within
sub-projects (LLVM and MLIR, MLIR and Flang), this is not desired. Also,
it is not possible to "un-use" a namespace once it is "used". Instead,
we should try to limit `using namespace` to implementation files (i.e.
*.cpp).

This patch removes `using namespace mlir;` from header files and adjusts
other files accordingly. In header and TableGen files, extra namespace
qualifier is added when referring to symbols defined in MLIR. Similar
approach is adopted in source files that didn't require many changes. In
files that would require a lot of changes, `using namespace mlir;` is
added instead.

This patch lowers STOP statement without arguments
and ERROR STOP. STOP statement with arguments lowering will
come in later patches ince it requires some expression lowering
to be added.
STOP statement is lowered to a runtime call.

Also makes sure we are creating a constant in the MLIR arith constant.

This patch is part of the upstreaming effort from fir-dev branch.

[Flang][Unit Test] Move the declaration of kindMap to the class

kindMap variable is declared in the Setup function but passed as
a reference to the firBuilder class. The firBuilder is declared in
the class and hence its lifetime exceeds that of kindMap. This can
lead to undefined behaviour. Move the kindMap variable into the class
to avoid this.

This is part of the upstreaming effort from the fir-dev branch in [1].
