This removes Python-related build variants, and adds
PYTHON3_PKG_BUILD:=0 and minor build adjustments (where appropriate),
for non-Python packages. There should be no changes to build output.
This also updates some include paths for python3-package.mk and/or
python3-host.mk to be relative to the package Makefile.

With CONFIG_CCACHE, $HOSTCC is 'ccache gcc' while $TARGET_CC points to a
single wrapper script. Compiling target binaries with ccache works, but
doesn't for host binaries, because we need to supply an argv array for
argc > 1 in the meson cross file.
Always pass an array for the c and c++ compiler, and while at it, do it
for the target as well - just to be on the safe side if that ever
changes.
Fixes#10982.
