-----------
ProxyObject's "get" IC should throw an error in case of non-callable
non-nullish trap
https://bugs.webkit.org/show_bug.cgi?id=251945
Reviewed by Yusuke Suzuki.
This change fixes IC helper for ProxyObject's "get" trap to implement GetMethod
per spec [1],
throwing a TypeError for non-callable non-nullish traps instead of forwarding
[[Get]] to receiver.
