libpcre: Allow building 16 and 32bit libpcre versions

This change allows selecting the 8, 16 or 32 bit version via PACKAGECONFIG.
By default only the 8bit version is built, this corresponds to the old behavior.

Some packages like Qt5 require the 16 bit version of libpcre.
After this change the corresponding layer can easily enable the version
needed via .bbappend.
