toolchain-external: unify LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS

With the alignment of toolchain library location in target and staging,
there is no need anymore for the distinction between LIB_EXTERNAL_LIBS and
USR_LIB_EXTERNAL_LIBS. Unify them into TOOLCHAIN_EXTERNAL_LIBS.

Related, update the help text of
BR2_TOOLCHAIN_EXTRA_TOOLCHAIN_EXTERNAL_LIBS.
