fix(runtime-dom): height and width of all elements should be set as attribute

[zh-lx]

close #9762

Height and width of all elements should be set as attribute.

When set width and height for a custom element with width and height as prop, the width and height should be set as attribute.

And for elements without width and height as prop such as div, it won't affect the real height and width of them, but should be displayed as an attribute on the dom in html. Just as the following image:

Thanks for the PR, but the root cause of this is that the previous logic was doing an early return and skipping the key in el check at the end. See 5b00286
