[feaLib] Fix name-table parsing for multibyte Mac encodings (#1196) (#4092)

* [feaLib] Fix name-table parsing for multibyte Mac encodings (#1196)

The unescape_string_ helper used to decode each "\XX" escape as a single
byte, which broke multibyte encodings (x_mac_japanese_ttx and friends)
whenever one character's bytes were split across escapes or across an
escape/literal-ASCII boundary (e.g. "\95F" = Shift-JIS 0x95 0x46 = 彦).

Build the full byte sequence from literal chars + \XX escapes and decode
it in one pass.

* Use bytearray.decode() directly
