Describe the bug

StyleX removed the attrs() function to keep it "simple". defineStyleX switched to props() function instead at #979. However, props() uses className instead of class, which is not completely compatible with vue. For <div>, className will be turned into class, but for <svg>, it wouldn't.

According to StyleX's document, we should write our own attrs().

Reproduction

defineStyleX, then use v-stylex for <svg>.
