enhances Compose input checks #6804

Is your feature request related to a problem? Please describe.
came across a similar issue as #6075:

import monai.transforms as mt

xform = mt.Compose(
    mt.LoadImage(image_only=True),
    mt.Orientation("RAS"),
)
xform("image.nii.gz")

no error message but the outcomes are different from the expected usage (with the [] in the Compose)

xform = mt.Compose([
    mt.LoadImage(image_only=True),
    mt.Orientation("RAS"),
])

this issue can be difficult to debug..
