Steps performed:
- Add "microsecond" and "nanosecond" to "intl/icu/data_filter.json".
- Run "icu_sources_data.py" to update the ICU data file.
- Run "update-tzdata.sh" to reapply the tzdata 2022f changes.
- Add "microsecond" and "nanosecond" to "SanctionedSimpleUnitIdentifiers.yaml".
- Run "make_intl_data.py units" to regenerate additional SpiderMonkey files.

Our previous heuristic no longer works, so we now have to patch ICU directly to
support detecting the approximately sign.

Replace "whitelist" and "blacklist" with "includelist" resp. "excludelist", because
the latter is now the preferred name in ICU and the ICU docs/examples are all using
the new names.

The `-/*` filter also removes the alias (`%%ALIAS`) and parent locale (`%%Parent`)
links, so we have to manually add them back when we're using `-/*`.
The ICU docs warn about this issue, but unfortunately that warning wasn't
present when we originally created our filter file, so this bug went unnoticed
for a long time.

This last part to support "calendar" requires a bit more code.
`GetCalendarDisplayName()` performs the following steps:
1. Validate the input matches the `type` nonterminal, per
CanonicalCodeForDisplayNames, step 4.a.
2. Then convert it to lower case, because ICU expects lower case names and it
needs to be in lower case for `LanguageTag::replaceUnicodeExtensionType()`.
3. Replace calendar name aliases with the preferred name, e.g. use "ethioaa"
instead of "ethiopic-amete-alem".
4. Check the input isn't too large, just in case ICU somehow doesn't properly
handle large string inputs.
5. Retrieve the old-style value of the calendar name, for example "gregorian"
for the calendar name "gregory".
6. And finally call `uldn_keyValueDisplayName` to search for the localised name.
Our ICU data file doesn't yet include calendar names. To include calendar names
we need to enable them in "data_filter.json", rebuild the ICU data file, and
then reapply the update for tzdata 2021a. (Reapplying the tzdata changed
"intl/tzdata/GIT-INFO", but otherwise didn't change any time zone files.)
Adding the calendar names to the ICU data file results in a slight increase of
the overall data file size (79,184 bytes).
The existing "calendar.js" test file was renamed to "month-calendar.js", so
the test file for the new "calendar" type can be named "calendar.js".

The change itself isn't important for us, because we don't use ICU's make-files,
but avoids confusion why additional changes were applied when running the update
script.

This removes a dependency on `pymake`, which is Python 2-only, and thoroughly unnecessary since we just use it to find assignments of the form `OBJECTS = ...`. We can replicate this logic by just isolating lines that begin with that literal string, and everything else can stay the same. This is definitionally more brittle than actually using a parser, but it works fine for now, and the original implementation wasn't significantly better (it didn't handle any form of dynamism, anything more complicated than a single unconditional assignment with a space-separated list of literal strings representing outputs, etc.)

"confusables" feature:
- Used in 'unicode/uspoof.h' for spoofing detection.
"stringprep" feature:
- Used in 'unicode/usprep.h' for RFC 3454 string preparation.
"unames" feature:
- Used in 'unicode/uchar.h' for `u_charName` to retrieve the name of a Unicode character.

ICU changes the numbering system of date formats which include an era marker
to "jpanyear". "jpanyear" is a rule-based numbering system and therefore the
RBNF data for the Japanese locale now need to be included.

Summary:
- ICU no longer supports removing resource files manually, instead the new data
filter builder needs to be used.
- This includes test data, which also must be preserved in ICU 64.
- umutex.h contains an implicit call to `new` in ICU64 which needs to be allowed
in check_vanilla_allocations.py.
- Drive-by: Make ICU with multiple jobs for faster rebuilds.
