pcre: use UCP in UTF mode

This fixes a serious bug affecting word-boundary and word-constituent regular

expressions when the desired match involves non-ASCII UTF8 characters.

* src/pcresearch.c: Set PCRE2_UCP together with PCRE2_UTF

* tests/pcre-utf8-w: New file.

* tests/Makefile.am (TESTS): Add it.

* NEWS (Bug fixes): Mention this.

* THANKS.in: Add Gro-Tsen and Karl Petterson.
