This reverts commit 609b524dd3ff36719b5c4470b85d37dcdadfb1f8. Reason for revert: Disable QualityScalingAllowed_QualityScalingEnabled on iOS. Original change's description: Before this CL quality scaling was conditioned on scaling settings provided by encoder. That should not be a requirement since encoder may not be aware of quality scaling which is a WebRTC feature. In M90 chromium HW encoders do not provide scaling settings (chromium:1179020). The default scaling settings provided by these encoders are not correct (b/181537172). This CL adds is_quality_scaling_allowed to VideoEncoderConfig. The flag is set to true in singlecast with normal video feed (not screen sharing) mode. If quality scaling is allowed it is enabled no matter whether scaling settings are present in encoder info or not. Setting from QualityScalingExperiment are used in case if not provided by encoder.

How to write code in the api/ directory
Mostly, just follow the regular style guide, but:
- Note that
api/code is not exempt from the “.hand.ccfiles come in pairs” rule, so if you declare something inapi/path/to/foo.h, it should be defined inapi/path/to/foo.cc. - Headers in
api/should, if possible, not#includeheaders outsideapi/. It’s not always possible to avoid this, but be aware that it adds to a small mountain of technical debt that we’re trying to shrink. .ccfiles inapi/, on the other hand, are free to#includeheaders outsideapi/.
That is, the preferred way for api/ code to access non-api/ code is to call
it from a .cc file, so that users of our API headers won’t transitively
#include non-public headers.
For headers in api/ that need to refer to non-public types, forward
declarations are often a lesser evil than including non-public header files. The
usual rules still apply, though.
.cc files in api/ should preferably be kept reasonably small. If a
substantial implementation is needed, consider putting it with our non-public
code, and just call it from the api/ .cc file.
