poco @1.12.2: Could NOT find PCRE2

[ryandesign (Ryan Carsten Schmidt)]

poco fails to build on all systems:

-- Using external sqlite, zlib, pcre2, expat, ...

-- Configuring incomplete, errors occurred!

After the update to poco 1.12.2, all ports using poco were revbumped, and fail to build. After this is fixed (by changing the pcre dependency to pcre2?) all the dependents that were revbumped will need to be manually rescheduled on all buildbot builders.
