fix(build): Fix sourcemaps, re-update metadata (#7550)

* fix(build): Revert "refactor: Remove $build$src infix from munged paths"

  This is a mostly-manual revert of commit
  06d78af to fix an issue where
  the generated sourcemaps are missing the inline copies of the
  original .ts source files.

* chore: Update metadata for 2020 Q3 release

  This is being done a second time as the revert of 06d78af causes a
  significant increase in the size of the build products.
