The 尤 and 冘 components may need unification

I suggest that we should unify the 尤 and 冘 components (with my preferred JP form where 丿 and 乚 touches) for all regions whenever possible, saving a bit of glyph space. There's nothing that says the 丿 and 乚 should not touch for CN/TW/HK locales. This is for Serif, the Sans version is [here](https://github.com/adobe-fonts/source-han-sans/issues/322) to avoid confusion.

Here are the characters to review:

The v1 reference is from a Source Han Serif fork called GenYoMincho (源樣明體 TW version) as I cannot install v1 and v2 at the same time. Glyphs are largely the same as v1 Serif, especially those which are removed v1 JP glyphs.

**LEGEND**
Green - the v1 glyph can be restored to replace all locales.
Blue - the v1 glyph can be restored to replace only the JP/KR/CN locales.
Purple - the v1 glyph cannot be restored whatsoever (has traditional print forms unsuitable for CN/TW/HK locales).
Red - the glyphs to be replaced by the v1 JP glyphs.
Orange - the glyphs to be adjusted.
Yellow - remap the TW form to the HK form.
Magenta/Pink - Replace with v2 JP/KR forms and remove existing glyph.
Cyan - Replace with v2 JP/KR forms.
Light green - replace with HK form and adjust glyph, then remove the CN glyph.
White - no change needed.

As for 黕 (marked dark grey), special case here: Rename the CN glyph to the JP glyph and adjust the 冘 portion such that it matches the JP aesthetics, then the old JP glyph can be renamed to TW/HK or just simply delete it in favour of the v1 TW glyph. My quote from earlier:

> Sorry if I commented quite late, but I kinda felt the CN glyph for 黕 should have been the JP glyph, but adjust that 冘 component such that the last stroke 乚 is closer to 丿, like the other "JP" glyph, then afterwards can remap to JP, KR and CN. Anyway, unless I am wrong, I think there's nothing that says the 乚 must not touch the 丿 for CN/TW/HK.

For 尤, I did put the character through my font list and it appears that maybe it should be treated separately for the CN region, but how the 丿 and 乚 strokes are applied is still inconsistent, especially between Sans and Serif. I probably suggest we review first and whether conforming all these characters containing 尤 to JP forms is acceptable for the CN region, and please comment with concrete evidence to prove otherwise.
