Update the XML docs for IComparisonOperators and implementing types

[tannergooding]

As called out in #64234 (comment)

The current XML docs for the IComparisonOperators operators are potentially confusing as they are:

///

Compares two values to determine which is less.

We should likely update this to something like

///

Returns a value that indicates whether a specified TSelf value is less than or equal to another specified TOther value.

and then update the docs of things like NFloat and the other types that are implementing, or will implement, IComparisonOperators accordingly.
