In some locales, currency data turns empty after currency list filtering
on Android. This leads v8's currency formatter to fall back to 3-letter
currency code instead of currency symbol (e.g. 'GBP' in en-GB).

Fix the ICU data trimming script to remove an empty Currency block after
filtering and rebuild ICU data files.

After data trimming, data/curr/en_GB.txt has empty "Currencies" block.
This prevents a locale fallback chain from being triggered for currency
symbols (en-GB => en-001 => en), leading all the currency symbols in en-GB
to be the last resort value (ISO 3-letter currency code). To avoid that,
trim_data.sh is revised to drop empty "Currencies" block entirely ('Missing'
triggers a fallback chain, but 'empty' goes straight to the last resort.)

Additional currency data fixes:

1. Serbian: RON and ROL display names are swapped. RON is the current
currency and should be included with a shorter display name.

2. Add a few more en-* locale variants to the locale list for currency.

Moreover, make_data_all.sh is updated to work wherever the Chromium
source tree is.

Finally, update the list of resources to remove from cast's ICU data
and rebuild it with ICU 60.  Added entries to cast-removed-resources.txt
are data for locale-variants that are not useful in Cast.

Our Cast Audio devices use a stripped down version of the android
icudtl.dat. Essentially the patch_locale.sh has been modified to keep in
things provided by Java, as cast doesn't have Java and needs there
resources.

On the other hand, a bunch of resources have been stripped from the
icudtl.dat to reduce its size because we are very constrained on that.

We have been using this icudtl.dat process for a long time now, and it's
throughly validated. However, we used to generate this in our internal
repo, which meant that we have to manually update it whenever chromium
updates their icudtl.dat.

This CL aims to intergrate the generation of the icudtl.dat in chromium,
so we no longer have to manually update in our internal repo.
