bitbake.conf: use ${TCMODE}-${TCLIBC} directory for CACHE

* move TCMODE and TCLIBC from defaultsetup.conf to bitbake.conf
* set CACHE as it was in defaultsetup.conf and drop it from defaultsetup.conf
* most if not all DISTROs are now including defaultsetup.conf and
  TCLIBC is pretty much expected to be always set correctly, e.g.:
  meta/recipes-core/systemd/systemd_243.2.bb:    if d.getVar('TCLIBC') == "musl":
  meta/recipes-devtools/gcc/gcc-runtime.inc:        if [ "${TCLIBC}" != "glibc" ]; then
  meta/recipes-devtools/gcc/libgcc.inc:     if [ "${TCLIBC}" != "glibc" ]; then
  meta/recipes-devtools/icecc-toolchain/nativesdk-icecc-toolchain_0.1.bb:ENV_NAME="${DISTRO}-${TCLIBC}-${SDK_ARCH}-@TARGET_PREFIX@${DISTRO_VERSION}.tar.gz"
  meta/recipes-devtools/valgrind/valgrind_3.15.0.bb:RRECOMMENDS_${PN} += "${TCLIBC}-dbg"
  meta/recipes-kernel/linux/kernel-devsrc.bb:RDEPENDS_${PN} = "bc python3 flex bison ${TCLIBC}-utils"

  meta/classes/buildhistory.bbclass:BUILDHISTORY_DIR_IMAGE = "${BUILDHISTORY_DIR}/images/${MACHINE_ARCH}/${TCLIBC}/${IMAGE_BASENAME}"
  meta/classes/cross-canadian.bbclass:    if d.getVar("TCLIBC") in [ 'baremetal', 'newlib' ]:
  meta/classes/kernel.bbclass:    tclibc = d.getVar('TCLIBC')
  meta/classes/toaster.bbclass:    BUILDHISTORY_DIR_IMAGE_BASE = e.data.expand("%s/images/${MACHINE_ARCH}/${TCLIBC}/"% BUILDHISTORY_DIR)
