Upload() should use PutObject API for uploading smaller objects

[AllanZhengYP]

Is your feature request related to a problem? Please describe.

As pointed out in #2581, the upload() in @aws-sdk/lib-storage always uses S3's multipart upload API. Users may use it for all kinds of usecases. However, the multipart upload API makes excessive amount of API calls compared to S3 PutObject API, especially when users only upload smaller objects.

Describe the solution you'd like

upload() should use only PutObject for object's size is detectable and smaller than given threshold.

Describe alternatives you've considered

Document the difference of upload() and s3.putObject() better -- this is not ideal experience.

Thanks for opening this feature request! I just want to point out (as I think that it isn't clear from the OP) that that the above is already implemented in v2 for s3.upload, but wasn't ported to the v3 implementation in lib-storage.

I've started working on this. I've got a working PR locally, however I still need to add some more tests for some edge-cases to make sure that everything is working correctly, and once I sort them out I'll open a PR - if there are no objections.
