feat(core): Filter out noisy GoogleTag error by default (#11208)

We received reports about this error

```
TypeError: Cannot redefine property: googletag
```

being thrown and reported to Sentry. It's a noisy error where we
strongly suspect that browser extensions interfere with our users' apps.
In an effort to quickly reduce noise, this patch adds the error message to
our SDK `inboundFilters` integration.
