REST API: Correct enum validation for numeric values.

Browse Source 
When validating `enum` values as `integer` or `number`, consider a number with a zero fractional part to be equivalent to an integer of the same value.

In `rest_are_values_equal()`, when comparing two values of type `int` or `float` (in any combination), first cast both of them to `float` and then compare.

This matches some test cases from the official JSON Schema test suite.

Follow-up to [50010].

Fixes #52932.
