Fix Memory Leaks

- Set `share_wgpu_instances` to `true` in Gyroflow Core.
- Added `kFxPropertyKey_IsThreadSafe` and `kFxPropertyKey_MayRemapTime` just in case. They shouldn't be needed, but the documentation is fairly unclear.
- We now correctly release the base64 data.
- Simplified `renderErrorMessageWithID`.
- We now use a temporary texture to avoid some weird Metal Texture memory leak. This is probably not the best way to do it, but I haven't worked out a better solution yet.
