fix(angular): Filter out TryCatch integration by default (#8367)

The `TryCatch` default integration interferes with the
`SentryErrorHander` error handler of the Angular(-Ivy) SDKs by catching
certain errors too early, before the Angular SDK-specific error handler
can catch them. This caused missing data on the event in some or
duplicated errors in other cases.

This fix filters out the `TryCatch` by default, as long as users didn't
set `defaultIntegrations` in their SDK init. Therefore, it makes the
previously provided
[workaround](#5417 (comment))
obsolete.
