Subject: [PATCH] [fix](sql-functions) provide setup data for HLL-function
 examples querying an undefined table

HLL_CARDINALITY, HLL_FROM_BASE64 and HLL_TO_BASE64 each show a `SELECT ... FROM <table>`
example with an expected result, but never define the table on the page, so the
examples cannot be run or reproduced ("table does not exist").

Add the missing CREATE TABLE + INSERT for each table (`test_uv` for HLL_CARDINALITY,
`test_hll` for the two base64 pages), built as aggregate tables with an HLL_UNION
column populated via hll_hash(), carried in a standard HTML comment
(`<!-- setup-sql ... -->`) before the example. As an HTML comment it does not change
the rendered page, and no documented expected output is modified.

Table contents were reverse-derived from the printed output (cardinality 3) and verified
end-to-end on the matching release cluster for every doc tree: version-4.x on 4.1.1,
version-3.x on 3.1.4, version-2.1 on 2.1.11 and dev/current on a master build. On every
tree the examples failed with "table does not exist" before and now resolve and match
the documented output.

Pages updated in EN + ZH across dev/current, version-4.x, version-3.x and version-2.1.
