[OE-core] [PATCH v2][zeus][master] harfbuzz: split libharfbuzz-subset.so to its own binary package

[Mikko Rapeli]

harfbuzz binary package size increased from 624608 bytes in yocto 2.5 to
1365431 bytes in yocto 3.0. Most of the size increase is in the new
libharfbuzz-subset.so* library
https://harfbuzz.github.io/utilities.html#utilities-command-line-hbsubset

Split it to its own binary package which will be installed if anyone needs it.
Effect to harfbuzz binary package size is:

-PKGSIZE = 1476271
+PKGSIZE = 1007424
