Support the format preamble format option in swc.minify

[mgol]

Describe the feature

See https://swc.rs/docs/configuration/minification#jscminifyformat

preamble, Currently noop

It should be possible to pass preamble. SWC should be able to insert it to the minified file without breaking source map associations.

Additional context

FWIW, jQuery is currently switching from UglifyJS to Terser in jquery/jquery#5258. We considered switching to SWC instead as it's way faster and optimizes better than Terser but the lack of the preamble option is a blocker for us at the moment.

@kdy1 Is this already in progress? If it's not urgent, maybe I can submit a PR next week?

Not yet, and it would be so great. Thank you in advance!
