harfbuzz: update to 14.2.0

Major release stream from 11.2.1 to 14.x. harfbuzz uses linear
versioning with each major bringing new shaping features and
improvements; 14.x is the current stable line.

Add PKG_BUILD_DEPENDS:=glib2/host: harfbuzz's meson.build pulls
glib_mkenums via the glib-2.0 pkg-config 'tool variable', and
OpenWrt's glib2 install rewrites gio-2.0.pc / glib-2.0.pc to point
at $(STAGING_DIR_HOSTPKG)/bin/glib-mkenums. That host binary is
only produced when glib2's host build runs, and without an
explicit dep on glib2/host the host build is skipped on clean CI
images that lack a system glib (failure message: "Program
/builder/staging_dir/hostpkg/bin/glib-mkenums found: NO -
Dependency 'glib-2.0' tool variable 'glib_mkenums' contains
erroneous value").
