build: wire up new CLDR generation tool within Bazel (#42230)

Introduces a few Starlark macros for running the new Bazel
CLDR generation tool. Wires up the new tool so that locales
are generated properly. Also updates the existing
`closure-locale` file to match the new output generated by the Bazel tool.

This commit also re-adds a few locale files that aren't
generated by CLDR 37, but have been accidentally left in
the repository as the Gulp script never removed old locales
from previous CLDR versions. This problem is solved with the
Bazel generation of locale files, but for now we re-add these
old CLDR 33 locale files to not break developers relying on these
(even though the locale data indicies are incorrect; but there might
be users accessing the data directly)
