类 missing from NSKO TTF, and/or wrong shape in TTC

[davelab6]

An internal b/333991947 bug report says when setting Android's system language as Korean and typing 类 anywhere. (ex. Messages, Chrome) then styling it with NotoSansCJK-Regular.ttc and NotoSerifCJK-Regular.ttc you see a wrong glyph shape.

On GF, it seems there is 类 in JP TC SC and not in the KO specific build of noto;

• https://fonts.google.com/noto/specimen/Noto+Sans+TC?query=noto+&preview.text=%E7%B1%BB%E9%A1%9E
• https://fonts.google.com/noto/specimen/Noto+Sans+SC?query=noto+&preview.text=%E7%B1%BB%E9%A1%9E
• https://fonts.google.com/noto/specimen/Noto+Sans+JP?query=noto+&preview.text=%E7%B1%BB%E9%A1%9E
• https://fonts.google.com/noto/specimen/Noto+Sans+KR?query=noto+&preview.text=%E7%B1%BB%E9%A1%9E

And I see there's a Korean specific character related to it (per https://www.compart.com/en/unicode/U+7C7B), 類

So, 类 should probably should in the KO font, with the same structure as its half-width form in left side of 類.

I didn't check the TTCs yet.

This character isn't in KS X 1002 which is one reason there's no K glyph in the font.

Great - then let's consider this blocked on the OT1.x 64k glyph limit and circle back when the OT2 version is undeway :)
