Deprecate Gorilla compression of non-float columns
Reasons:

1. The original Gorilla paper proposed a compression schema for pairs of
   time stamps and double-precision FP values. ClickHouse's Gorilla
   codec only implements compression of the latter and it does not
   impose any data type restrictions.
   - Data types != Float* or (U)Int* (e.g. Decimal, Point etc.) are
     definitely not supposed to be used with Gorilla.
   - (U)Int* types are debatable. The paper only considers
     integers-stored-as-FP-values, a practical use case for which
     Gorilla works well. Standalone integers are not considered which
     makes them at least suspicious.

2. Achieve consistency with FPC, another specialized floating-point
   timeseries codec, which rejects non-float data.

3. On practical datasets, ZSTD is often "good enough" (**) so it should
   be okay to disincentive non-ZSTD codecs a little bit. If needed,
   Delta and DoubleDelta codecs are viable alternative for slowly
   changing (time-series-like) integer sequences.

Since on-prem and hosted users may still have Gorilla-compressed
non-float data, this combination is only deprecated for now. No warning
or error will be emitted. Users are encouraged to migrate
Gorilla-compressed non-float data to an alternative codec. It is planned
to treat Gorilla-compressed non-float columns as "suspicious" six months
after this commit (i.e. in v23.6). Even then, it will still be possible
to set "allow_suspicious_codecs = true" and read and write
Gorilla-compressed non-float data.

(*) Sec. 4.1.2, "Gorilla restricts the value element in its tuple to a
    double floating point type.", https://doi.org/10.14778/2824032.2824078

Update documentation example for REPLACE TABLE
The example statement for `REPLACE TABLE` using a `SELECT` query does not run as written. The example was missing a query engine, engine options, and the `AS` keyword, all of which seem required to replace a table with the output of some query.

Add a codec AES_128_GCM_SIV for encrypting columns on disk (#19896)
* Add a codec Encrypted() for encrypting columns on disk

While this is implemented as a compression codec, it does not actually compress data. It instead encrypts data on disk. The key is obtained by executing a user-specified command at the server startup, or if it's not specified the codec refuses to process any data. For now the only supported cipher is 'AES-128-GCM-SIV'.
