Fix the logic to get the max supported encoding level.

On some Android devices, the return value of

```
MediaCodecInfo.getCapabilitiesForType(mimeType).profileLevels
```

contains one entry for each encoding profile, like <profile, maxSupportedLevel>

but on some other devices, there are multiple entries for the same profile,

like <HIGH_PROFILE, LEVEL1>, <HIGH_PROFILE, LEVEL2>, <HIGH_PROFILE, LEVEL3>,
where we need to iterate through all the entries and find the max.
