…ks on punctuations, a=testonly

Automatic update from web-platform-tests
text-emphasis: Do not paint emphasis marks on punctuations

* Do not paint emphasis marks on punctuations
* Do not use IDEOGRAPHIC FULL STOP for text-combine placeholder
  It's a punctuation.  Use HIRAGANA LETTER A instead.
* Do not paint emphasis marks on generated ellipsis symbols just in case
  It's always a punctuation now. But we might support arbitrary string
  in the future.

* Update text-emphasis-punctuation-1.html so that it uses Ahem font
  Without this change, the test had pixel glitches on Chromium.

The new behavior matches to Firefox.
