Wrong CN mapping for 県 (U+770C)

Also attached is the STSong font as reference.

For 県, I don't know why Changzhou Sinotype partially used the SimHei font as a reference when designing the CN glyphs, when SimHei is wrong on this character. Suggest to remove the current CN glyph and remap it to TW/HK.

For 釋, CN is currently mapped to JP, which is incorrect because the bottom right part, 幸, essentially, the bottom stroke must be longer than the second-most bottom stroke in 新字形. Suggest to remap it to TW/HK.

**EDIT:** Further details for 釋 and 鸅 is [here](https://github.com/adobe-fonts/source-han-sans/issues/388), for consolidation purposes, accordingly I have deleted my recent comment.

Source Han Serif CN is fine.
