[v2] tcmode-default: add rust to the default toolchains

["Randy MacLeod" <randy.macleod@windriver.com>]

Remove the rust_versions.inc file and put it's content
in tcmode-default.inc is done for other toolchains.

Rename RUST_VERSION to RUSTVERSION to adhere to the
naming format used for other languages.
