Runtime: API proposal: add IEnumerable<byte> overload to System.IO.File.WriteAllBytesAsync API

[zeroskyx]

Greetings,

the current API for System.IO.WriteAllBytesAsync only supports byte[] as an input.

This prevents the usage of other buffer formats such as ImmutableArray<>.

It would be great if we had an additional overload with IEnumerable<byte> for both the Async and the Sync version of write all bytes, just as System.IO.WriteAllTextAsync does.

I imagine one of the problems with that API would be that you'd need to still enumerate the bytes to write them in a block or write each byte individually and that would be slow.

Your best bet for ImmutableArray<byte> is probably ImmutableArray<byte>.AsMemory() and FileStream.WriteAsync(ReadOnlyMemory<Byte>, CancellationToken).
