* Read interface IList.Count once rather than per iteration
Inspired by #9962, read .Count once rather than once per loop iteration.
* Use nameof() instead of ToString()
Use constant nameof() on enum value, rather than runtime ToString().
* Right-size dictionary
Initialize dictionary with a fixed number of elements to the number of elements it contains.
* Use DisposeAsync()
Use DisposeAsync() on FileBufferingReadStream in input formatters.
* Override DisposeAsync()
Override DisposeAsync() to call DisposeAsync() on the inner stream.
* Use GetValueOrDefault() for content-length
Use GetValueOrDefault() to read the content length once instead of checking HasValue once and Value up to three times.
* Update Microsoft.AspNetCore.WebUtilities.netcoreapp3.0.cs
Add DisposeAsync().
* Use DisposeAsync()
Use DisposeAsync() on transcoding streams as other formatters do.
* Avoid buffering during input formatting for longer than necessary
EnableRewind uses FileBufferingReadStream which is not disposed until the response is completed.
This results in holding on to internal buffers for significantly longer than necessary. Changing it
to return the buffers immediately improved the allocations and throughput.
