Span Filter Option ignoreSpans

### Problem Statement

Hi, there's no way to filter out spans, like beforeSpan in javascript (which is getting deprecated in v9 JS SDK)

### Solution Brainstorm

```
Sentry.init({
ignorSpans: ['span_description']
})
```

or it could take a span attribute that represents multiple, like something for this span type that always says 'browser', maybe user wants to remove all spans that say browser.

or maybe user wants 1 http spans for a http request but not all the sub spans here like .proxy .dns etc.

regex would work nice
