[JSC] Wasm GC: Simplify RTT::isStrictSubRTT C++ and JIT code
https://bugs.webkit.org/show_bug.cgi?id=294850
rdar://154099633
Reviewed by Keith Miller.
The special case for parent.displaySize() == 0 is unnecessary because
when parent.displaySize() is 0, then:
1. displaySize() <= parent.displaySize() is always false (since
displaySize() > 0)
2. displaySize() - parent.displaySize() - 1 is equivalent to displaySize() - 1)
Then, we can further simplify since displaySize() check becomes
redundant with displaySize() <= parent.displaySize().
So simplify this code and remove the unnecessary branches.
