LOG: 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.
