Jakob Gruber 054f5f69e5 Revert "Add counter to track Date::getTimezoneOffset()." 
This reverts commit 14ebea15a4.

Reason for revert: CountUsage() can't be called without a C entry frame.

Note this counter was never hooked up in chromium. Besides removing the
problematic CountUsage() call, this CL also makes the call path more
robust against similar future issues by adding {gc,handle,js} disallow
scopes.
