315906b380 Add ability to parse hours/months without leading zeros
Recently I was looking into one dataset, that has such format.

So I've changed the meaning of the following formatters for
formatDateTime()/parseDateTime(), like in other implementations [1]:

- %l/%k - to handle hours without leading zeros
- %c - handle months without leading zeros

  [1]: https://www.php.net/strftime

And since this is kind of behaviour change (even though it is unlikely
will break something), there is a new setting to control this new
behaviour:
- parsedatetime_enable_format_without_leading_zeros=1 (default ON)
- formatdatetime_enable_format_without_leading_zeros=0 (default OFF, since this could change users output)

Remove overflow setting
Reason 1:
- https://github.com/ClickHouse/ClickHouse/pull/55696#issuecomment-1774130793
  Basically: Setting `date_time_overflow_behavior` applies only to
  conversions between Date <-> Date32 <-> DateTime <-> DateTime64 but
  it does not control the behavior of functions.

Reason 2:
- It's overkill (even if well-intented overkill). ClickHouse generally
  has a garbage in - garbate out philosophy, so that should be the
  default behavior which corresponds to behavior "ignore". Moreover,
  function 'fromDaysSinceYearZero()' mostly exists for compatibility /
  parity with MySQL and MySQL takes the same stance.
