  [mlir] NFC - Refactor and expose a parsing helper for OffsetSizeAndStrideInterface

Parse trailing part of an op of the form:
```
  <optional-offset-prefix>`[` offset-list `]`
  <optional-size-prefix>`[` size-list `]`
  <optional-stride-prefix>[` stride-list `]`
```
Each entry in the offset, size and stride list either resolves to an integer
constant or an operand of index type.
Constants are added to the `result` as named integer array attributes with
name `OffsetSizeAndStrideOpInterface::getStaticOffsetsAttrName()` (resp.
`getStaticSizesAttrName()`, `getStaticStridesAttrName()`).

Append the number of offset, size and stride operands to `segmentSizes`
before adding it to `result` as the named attribute:
`OpTrait::AttrSizedOperandSegments<void>::getOperandSegmentSizeAttr()`.
Offset, size and stride operands resolution occurs after `preResolutionFn`
to give a chance to leading operands to resolve first, after parsing the
types.
```
ParseResult parseOffsetsSizesAndStrides(
    OpAsmParser &parser, OperationState &result, ArrayRef<int> segmentSizes,
    llvm::function_ref<ParseResult(OpAsmParser &, OperationState &)>
        preResolutionFn = nullptr,
    llvm::function_ref<ParseResult(OpAsmParser &)> parseOptionalOffsetPrefix =
        nullptr,
    llvm::function_ref<ParseResult(OpAsmParser &)> parseOptionalSizePrefix =
        nullptr,
    llvm::function_ref<ParseResult(OpAsmParser &)> parseOptionalStridePrefix =
        nullptr);
```
