storage: upload_from_filename() should use streams (upload() does)

[awoimbee]

This is an issue when uploading large files (it hogs ram until it or the system crashes).

Seems easy to fix: simply remove this line

But then another issue arises, Storage.upload() accepts a synchronous fileobject, but not at async one:

async with aiofiles.open(f"my_file", "rb") as f:
    await gcs_clt.upload(BUCKET_NAME, remote_path, f, timeout=None)
# TypeError: unsupported upload type: "<class 'aiofiles.threadpool.binary.AsyncBufferedReader'>"

with open(f"my_file", "rb") as f:
    await gcs_clt.upload(BUCKET_NAME, remote_path, f, timeout=None)
# All good !

Unfortunately, this was done intentionally to avoid this bug. We would definitely be interested in a solution which uses streams without triggering that issue!
