Simplify diagnostic error management for MLIR properties API (NFC) (#67409)
This is a follow-up to 8c2bff1ab929 which lazy-initialized the
diagnostic and removed the need to dynamically abandon() an
InFlightDiagnostic. This further simplifies the code to not needed to
return a reference to an InFlightDiagnostic and instead eagerly emit
errors.

Also use `emitError` as name instead of `getDiag` which seems more
explicit and in-line with the common usage.

5e118f933b Introduce MLIR Op Properties
This new features enabled to dedicate custom storage inline within operations.
This storage can be used as an alternative to attributes to store data that is
specific to an operation. Attribute can also be stored inside the properties
storage if desired, but any kind of data can be present as well. This offers
a way to store and mutate data without uniquing in the Context like Attribute.
See the OpPropertiesTest.cpp for an example where a struct with a
std::vector<> is attached to an operation and mutated in-place:

struct TestProperties {
  int a = -1;
  float b = -1.;
  std::vector<int64_t> array = {-33};
};

More complex scheme (including reference-counting) are also possible.

The only constraint to enable storing a C++ object as "properties" on an
operation is to implement three functions:

- convert from the candidate object to an Attribute
- convert from the Attribute to the candidate object
- hash the object

Optional the parsing and printing can also be customized with 2 extra
functions.

A new options is introduced to ODS to allow dialects to specify:

  let usePropertiesForAttributes = 1;

When set to true, the inherent attributes for all the ops in this dialect
will be using properties instead of being stored alongside discardable
attributes.
The TestDialect showcases this feature.

Another change is that we introduce new APIs on the Operation class
to access separately the inherent attributes from the discardable ones.
We envision deprecating and removing the `getAttr()`, `getAttrsDictionary()`,
and other similar method which don't make the distinction explicit, leading
to an entirely separate namespace for discardable attributes.

This reverts commit d572cd1b067f1177a981a4711bf2e501eaa8117b.

Some bots are broken and investigation is needed before relanding.

5cdc2bbc75 [mlir] Move SymbolOpInterfaces "classof" check to a proper "extraClassOf" interface field
SymbolOpInterface overrides the base classof to provide support
for optionally implementing the interface. This is currently placed
in the extraClassDeclarations, but that is kind of awkard given that
it requires underlying knowledge of how the base classof is implemented.
This commit adds a proper "extraClassOf" field to allow interfaces to
implement this, which abstracts away the default classof logic.

f570cc173d [mlir][NFC] Move CodeGenHelpers.cpp from mlir-tblgen to TableGen library
Its header was already part of the TableGen library, but unusable as uses of its functions or classes would lead to undefined references when linking. This fixes that.
