[mlir] Add property combinators, initial ODS support (#94732)
While we have had a Properties.td that allowed for defining
non-attribute-backed properties, such properties were not plumbed
through the basic autogeneration facilities available to attributes,
forcing those who want to migrate to the new system to write such code
by hand.

## Potentially breaking changes

- The `setFoo()` methods on `Properties` struct no longer take their
inputs by const reference. Those wishing to pass non-owned values of a
property by reference to constructors and setters should set the
interface type to `const [storageType]&`
- Adapters and operations now define getters and setters for properties
listed in ODS, which may conflict with custom getters.
- Builders now include properties listed in ODS specifications,
potentially conflicting with custom builders with the same type
signature.

## Extensions to the `Property` class

This commit  adds several fields to the `Property` class, including:
- `parser`, `optionalParser`, and `printer` (for parsing/printing
properties of a given type in ODS syntax)
- `storageTypeValueOverride`, an extension of `defaultValue` to allow
the storage and interface type defaults to differ
- `baseProperty` (allowing for classes like `DefaultValuedProperty`)

Existing fields have also had their documentation comments updated.

This commit does not add a `PropertyConstraint` analogous to
`AttrConstraint`, but this is a natural evolution of the work here.

This commit also adds the concrete property kinds `I32Property`,
`I64Property`, `UnitProperty` (and special handling for it like for
UnitAttr), and `BoolProperty`.

## Property combinators

`Properties.td` also now includes several ways to combine properties.

One is `ArrayProperty<Property elem>`, which now stores a
variable-length array of some property as
`SmallVector<elem.storageType>` and uses `ArrayRef<elem.storageType>` as
its interface type. It has `IntArrayProperty` subclasses that change its
conversion to attributes to use `DenseI[N]Attr`s instead of an
`ArrayAttr`.

Similarly, `OptionalProperty<Property p>` wraps a property's storage in
`std::optional<>` and adds a `std::nullopt` default value. In the case
where the underlying property can be parsed optionally but doesn't have
its own default value, `OptionalProperty` can piggyback off the optional
parser to produce a cleaner syntax, as opposed to its general form,
which is either `none` or `some<[value]>`.

(Note that `OptionalProperty` can be nested if desired).

  ## Autogeneration changes

Operations and adaptors now support getters and setters for properties
like those for attributes. Unlike for attributes, there aren't separate
value and attribute forms, since there is no `FooAttr()` available for a
`getFooAttr()` to return.

The largest change is to operation formats. Previously, properties could
only be used in custom directives. Now, they can be used anywhere an
attribute could be used, and have parsers and printers defined in their
tablegen records.

These updates include special `UnitProperty` logic like that used for
`UnitAttr`.

## Misc.

Some attempt has been made to test the new functionality.

This commit takes tentative steps towards updating the documentation to
account for properties. A full update will be in order once any followup
work has been completed and the interfaces have stabilized.

363b655920 Finish renaming getOperandSegmentSizeAttr() from operand_segment_sizes to operandSegmentSizes
This renaming started with the native ODS support for properties, this is completing it.

A mass automated textual rename seems safe for most codebases.
Drop also the ods prefix to keep the accessors the same as they were before
this change:
 properties.odsOperandSegmentSizes
reverts back to:
 properties.operandSegementSizes

The ODS prefix was creating divergence between all the places and make it harder to
be consistent.

8a7a7137ff [mlir] somewhat decompose TestDialect.cpp
TestDialect.cpp along with the ODS-generated files amounts to around
100k LoC and takes a significant amount of time to compile. Factor out
the test ops related to testing the sytnax and assembly format, which
are a relatively large and well delimited group, into a separate set of
files.

Also factor out dialect interfaces into a separate file.
