hoxyq c65ae2687c refactor[ci/build]: preserve header format in artifacts (#27671)
In order to make Haste work with React's artifacts, It is important to
keep headers in this format:
```
/**
* ...
...
* ...
*/
```

For optimization purposes, Closure compiler will actually modify these
headers by removing * prefixes, which is expected.
We should pass sources to the compiler without license headers, with
these changes the current flow will be:
1. Apply top-level definitions. For UMD-bundles, for example, or
DEV-only bundles (e. g. `if (__DEV__) { ...`)
2. Apply licence headers for artifacts with sourcemaps: oss-production
and oss-profiling bundles, they don't need to preserve the header format
to comply with Haste. We need to apply these headers before passing
sources to Closure, so it can build correct mappings for sourcemaps.
3. Pass these sources to closure compiler for minification and
sourcemaps building.
4. Apply licence headers for artifacts without sourcemaps: dev bundles,
fb bundles. This way the header style will be preserved and not changed
by Closure.
