encoding/charmap: update UCM spec file URL prefix

UCM spec files used by encoding/maketables.go moved from
source.icu-project.org to github.com, and maketables is failing.

The new repo is at
https://github.com/unicode-org/icu-data/tree/main/charset/data/ucm.

Changed all UCM mappings to use the "raw endpoint" prefix,
https://raw.githubusercontent.com/unicode-org/icu-data/main/charset/data/ucm/….

Fixes golang/go#64504.

encoding/japanese, language: shorten very long sub-test names

Some of the generated sub-test names end up being excessively long,
which doesn't mix well with them being stored as test IDs that track
test runs over time. Replacing test case names with numbers harms
their readability, so start by trimming a few that end up being 500+
bytes in length.

internal/export/idna: make more space for mapping index

This prepares for an upcoming Unicode upgrade.

Beyond Unicode 13 the size of mappings will grow beyond
what can be represented in the allocated 13 bits. Instread
of doubling the size of info, we introduce a table of indices
into the mappings data. This also allows us to remove the
length byte, reducing the overhead of introducing this new
table.

This change allows for about a 5x growth of the number
of mappings, which should suffice for the foreseeable
future.

definition of the minor and patch versions of this module are now
