This is to replace the script test in core that is used
to verify the generation, but it interupts the flow of
automation as they require manual upgrades.
This brute-force approach is better anyway.

The test is removed in favor of one that fits within the

Updates documentation and other changes not related to
a Unicode upgrade to minimize the diff.

This CL also updates gen.go to no longer copy packages
into the vendor directory. Henceforth, go mod vendor
should be used to copy packages.

The changes in Unicode 11 exposes a bug in maketables.go.
We update the Unicode 10 tables using a new generator
to minimize the changes upgrading to Unicode 11.

This change switches over the generation from core to that in
x/text. To properly update the tables one needs to run the generate
in x/text anyway, so this makes that official.

The RangeTable generator in x/text also generates slightly compacter
tables.

IDNA still uses the old test format. The new
format tests more cases. The 11 format causes
test failure, but only for erroneous input that
result in errors. The package will in all such
cases still report an error, but the value result
