chroot_lib: Remove ChrootManager

This was originally added in crrev.com/c/224852 to support incremental
builds by detecting local build failures.  This functionality has been
replaced by a more robust implementation, so the LKGM-based method is
now counterproductive.  Also remove the entire chroot_lib module, since
there aren't any other users of it.

make_chroot: Remove unused toolchain overlay support

cros_sdk can pass in an additional overlay tarball to unpack on top of
the chroot.  This hasn't been used in cros_sdk since 2016 and is being
removed, so no need to support it in make_chroot.sh, either.

cros_sdk: Remove unused toolchain overlay support

The --toolchains argument downloads additional tarball(s) and unpacks
them on top of the initial extracted chroot.  The --board argument
preselects toolchains for a particular board and then works the same as
--toolchains.  Both of these are looking for files that were turned off
in March 2016 (see crrev.com/c/332862).  Nobody has complained about the
lack since then, so let's just remove this code.

Lowering priority since the remaining work is likely to wait for an intern this summer.
