Fix Buffer warnings during build (#10495)

The warnings about use of the unsafe Buffer constructor have been
addressed by package updates and patches.

The updates were:
 * `gulp-sourcemaps` was updated from v2 to v3, and was patched to
replace remaining uses of the `Buffer` constructor
   * Upstream PR: https://github.com/gulp-sourcemaps/gulp-sourcemaps/pull/388
 * The transitive dependency `yazl` was updated from v2.4.3 to v2.5.1
in the lockfile.
 * The abandoned packages `combine-source-map` and `inline-source-map`
were patched.
