Bug#991761: rust-swc-core: ecma crates ready to enable (ITP #991761)

Hi Jonas,

Answering below

Regarding precomputed-map. MR ready for debcargo-conf: https://salsa.debian.org/rust-team/debcargo-conf/-/merge_requests/1283 (ITP #1142523)


Now: ecma crates. Changed now to 3 atomic commits (as requested) on debian/enable-ecma-crates-v2 in my fork: https://salsa.debian.org/mendezr/rust-swc-core/-/commits/debian/enable-ecma-crates-v2

I took a look to the the icu_properties exclusion (to enable ecma_minifier/transforms) but it is a different matter in scope, so I think it is better to work on that on a different batch of work. The dev-dep chain cascades and rollup doesn't need those, my main objective to unblock rollup-v4

Please, have a look,
Juan
