    Op properties when used with python are broken in multiple ways:
 
1. They cannot be set when constructing an op from python, they result in dead args. For example, take `FatRawBufferCastOp`, it has `boundsCheck`  and `resetOffset` as props, and the resulting python class init is:
```
  def __init__(self, source, boundsCheck, resetOffset, *, validBytes=None, cacheSwizzleStride=None, loc=None, ip=None):
    operands = []
    results = []
    attributes = {}
    regions = None
    operands.append(source)
 operands.append(validBytes)
    operands.append(cacheSwizzleStride)
 _ods_context = _ods_get_default_loc_context(loc)
    _ods_successors = None
    super().__init__(self.OPERATION_NAME, self._ODS_REGIONS, self._ODS_OPERAND_SEGMENTS, self._ODS_RESULT_SEGMENTS, attributes=attributes, operands=operands, successors=_ods_successors, regions=regions, loc=loc, ip=ip)
```
2. Properties cannot be set from python (unless they are also an inherent attr).
