pcre2: import pcre2 from packages feed

pcre2 is needed by newer selinux versions, so it needs to be in the base
repository.

+               Enable JIT (Just-In-Time) compiler support.
+
+               Just-in-time compiling is a heavyweight optimization that can greatly
+               speed up pattern matching. However, it comes at the cost of extra
+               processing before the match is performed, so it is of most benefit when
+               the same pattern is going to be matched many times. This does not
+               necessarily mean many calls of a matching function; if the pattern is
+               not anchored, matching attempts may take place many times at various
+               positions in the subject, even for a single call. Therefore, if the
+               subject string is very long, it may still pay to use JIT even for
+               one-off matches. JIT support is available for all of the 8-bit, 16-bit
+               and 32-bit PCRE2 libraries and adds about 100KB to the resulting
+               libpcre2.so. JIT support applies only to the traditional Perl-compatible
+               matching function. It does not apply when the DFA matching function is
+               being used.
+
+               Enabling this option can give an about 10x performance increase on JIT
+               operations. It can be desireable for e.g. high performance Apache
+               mod_rewrite or HA-Proxy reqrep operations.
+
+               However, JIT should _only_ be enabled on architectures that are supported.
+               Enabling JIT on unsupported platforms will result in a compilation
+               failure. A list of supported architectures can be found here:
