Kristiyan Kostadinov fb65ad157c perf(platform-server): speed up resolution of base (#61392) 
The `getBaseHref` method is called several times per request and currently queries through the entire document. We can speed it up by taking advantage of the fact that the `<base>` can only be a direct child of the `<head>` and is usually defined towards the beginning. Below are some benchmarks for a "Hello world" app before and after this change.

### Before:
```
Running 60s test @ http://localhost:4202
100 connections with 10 pipelining factor
