Fix PCRE2_DEBUG for multi-configuration builds (#542)

* Add support for Ninja Multi-Config generator on all platforms
* Ensure one build job is using CMake 3.15
* Provide a build type (Debug or RelWithDebInfo) on all CMake builds
* Ensure PCRE2_DEBUG=ON is set for: dev.yml builds which use the
  Release configuration
