Subject: [PATCH] fix(browser): check supportedEntryTypes before caling the
 function (#13541)

`PerformanceObserver` is available on iOS 11 and later, but
the `supportedEntryTypes` method is available on iOS 13 and later.

ref:
https://developer.mozilla.org/en-US/docs/Web/API/PerformanceObserver

Therefore, a runtime error will occur if we use Sentry on iOS 11 or iOS
12.
