Node SEA ESM support

[guoh27]

What is the problem this feature will solve?

Nodejs version 20.15.0,
I have a .mjs file, use node --experimental-sea-config sea-config.json pack as a blob,
and then npx postject hello NODE_SEA_BLOB sea-prep.blob --sentinel-fuse NODE_SEA_FUSE_fce680ab2cc467b6e072b8b5df1996b2 successful,
but ./hello will throw Require a ESM error.
So, packing ESM module into SEA single executable is not available now.

What is the feature you are proposing to solve the problem?

Packing ESM module as a single exeutable.

What alternatives have you considered?

Another feature request is: bake v8 options into executable to run with them on, like pkg's --options argument

according to lib/internal/util/embedding.js#L19

Don’t forget the --options parameter like pkg:
