Re-organize the variants of `libtcg-helpers-*.bc` as such: * `libtcg-helpers-full-$ARCH.bc`: unchanged, contains all helper function with their bodies and all CSVs. * `libtcg-helpers-declarations-only-$ARCH.bc`: all helper functions have been turned to declarations. All CSVs (except a couple of special ones) have been dropped. * `libtcg-helpers-to-inline-$ARCH.bc`: only functions with the `revng_inline` section retain their body. Only CSVs that are used by these functions are present. Lift now loads only the `declarations-only` variant of helpers, as their body is not required until `inline-helpers`. In `inline-helpers` the `to-inline` variant is loaded and linked, which then allows the helpers to be inlined.
