[SR] Fix crashing MediaCodec and use density to determine recording resolution

[romtsn]

#skip-changelog

📜 Description

• Moves away from using a static height, but rather determine the recording size based on density (use 1x=mdpi for now, which means 2280x1080 will translate to something like 840x400)
• Fixes crashing MediaCodec on some devices, because we were not rounding height and width so they're divisible by 16 (pixel block size, which codecs work on)
• Increases default bitrate because 20k bps is of very low quality (we'll introduce different quality levels in the future, so it's easier for customers to chose from low|medium|high rather than picking arbitrary values)
• Fixes out-of-sync viewHierarchy in some cases by setting it to null immediately so it's not used for a later (maybe irrelevant) screenshot
