Within Google, closure compiler is used for dealing with translations.
We generate a closure-compatible locale file that allows for
registration within Angular, so that Closure i18n works well together
with Angular applications. Closure compiler does not limit its
locales to BCP47-canonical locale identifiers. This commit updates
the generation logic so that we also support deprecated (but aliased)
locale identifiers, or other aliases which are likely used within
Closure. We use CLDR's alias supplemental data for this. It instructs
us to alias `iw` to `he` for example. `iw` is still supported in Closure.
Note that we do not manually extract all locales supported in Closure;
instead we only support the CLDR canonical locales (as done before) +
common aliases that CLDR provides data for. We are not aware of other
locale aliases within Closure that wouldn't be part of the CLDR aliases.
If there would be, then Angular/Closure would fail accordingly.

In the past, the closure file has been generated so that all individual
locale files were imported individually. This resulted in a huge
slow-down in g3 due to the large amount of imports.
With 90bd984ff7 this changed so that we
inline the locale data for the g3 closure locale file. Also the file
only contained data for locales being supported by Closure. For this a
list of locales has been extracted from Closure Compiler, as well as a
list of locale aliases.
This logic is prone to CLDR version updates, and also broke as part of
the Gulp -> Bazel migration where this logic has been slightly modified
but caused issues in G3. e.g. a locale `zh-Hant` was requested in g3,
but the locale data had the name of the alias locale that provided the
data at index zero (which represents the locale name). Note that the
locale names at index zero always could differentiate from the requested
`goog.LOCALE` due to the aliasing logic. This just didn't come up before.
We simplify this logic by generating a `goog.LOCALE` case for all
locales CLDR provides data for. We don't need to bother about aliasing
because with the refactorings to the CLDR generation tool, all locales
are built (which also captures the aliases), and we can generate the locale
file on the fly (which has not been done before).

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)

Historically files to be formatted were added to a listing (via matchers)
to be included in formatting. Instead, this change begins efforts to
instead include all files in format enforcement, relying instead on an
opt out methodology.

The locale data extraction has been modified to include the default
currency code in the generated locale data. This commit updates these
generated files accordingly.

When directionality data was added to @angular/common locales, only
the externally used locales were updated. We need to additionally
update the closure locales which are synced into google3.

This fix is for the issue below when compiling I18N Angular apps using closure.
For certain locales closure converts the input locale id to a different equivalent locale string. For example if the input locale is 'id'(for Indonesia) goog.LOCALE is set to 'in' and the closure locale data is registered only for 'in'. The Angular compiler uses the original input locale string, 'id' to set the LOCALE_ID token and there is a mismatch of locale used to register and locale used when requesting the locale data.
The fix is for the closure-locale.ts code to register the locale data for all equivalent locales names so that it doesn't matter what goog.LOCALE is actually set to.
