This allows discouraging the use of specific build methods of an op by having TableGen generate C++ code, instructing the C++ compiler to warn on use of the `build` method.
The implementation uses the C++14 `[[deprecated(...)]]`` for this purpose. I considered using `LLVM_DEPRECATED`, but thought requiring a fix-it was not necassery, nor would the syntax in ODS have been very nice.
My motivation for this change is that in the future I'd like to deprecate the use `build` methods in the LLVM Dialect, not using explicit pointer types for ops such as `llvm.load` or `llvm.alloca`, which makes the code not future proof for opaque pointers. In-tree has to be clean first before I could commit such a change of course, but I thought the initial infrastructure change could already be submitted.

This is part of an effort to migrate from llvm::Optional to
std::optional. This patch changes the way mlir-tblgen generates .inc
files, and modifies tests and documentation appropriately. It is a "no
compromises" patch, and doesn't leave the user with an unpleasant mix of
llvm::Optional and std::optional.
A non-trivial change has been made to ControlFlowInterfaces to split one
constructor into two, relating to a build failure on Windows.

This moves the documentation for defining dialects, attributes/types,
and operations into a new `DefiningDialects` folder. This helps to
keep the documentation grouped together, making it easier to find
related documentation.
