New flag: PCRE2_EXTRA_TURKISH_CASING, and pre-pattern flag
(*TURKISH_CASING).
Also added a pre-pattern flag (*CASELESS_RESTRICT) for this existing
flag.
Since a608946 (Additional PCRE2_EXTRA_ASCII_xxx code, 2023-02-01)
PCRE2_EXTRA_ASCII_BSD could be used to restrict \d to ASCII causing
the following inconsistent behaviour in UCP mode.
PCRE2 version 10.43-DEV 2023-01-15

It has been suggested[1] that the change to match \p{Nd} when Unicode
is enabled for [:digit:] might had been unintentional and a bug, as
[:digit:] should be able to be POSIX compatible, so add a new flag
PCRE2_EXTRA_ASCII_DIGIT to avoid changing its definition in UCP mode.
