mrambacher 37ec9d0c12 Improve performance of SliceTransform::AsString (#9401)
Summary:
1. Removed the options from the Capped/Fixed SliceTransforms.  Instead these classes are created with id.number.  This allows the GetID() id to be calculated and stored at class construction time.  This change puts the construction back to similar to how it was prior to the Customizable changes for SliceTransform.

2.  Improve the performance of AsString by using the ID only if there are no option properties (which is the case for all of the builtin transforms).

Ran tests of calling AsString in a loop 5M times and found approximately a 10x performance increase vs the original code.
