This improves usability to simply call:
cmake -P cmake/scripts/GenerateLexersParsers.cmake
instead of doing the entire CMake configuration phase and then executing
some target to generate files.
- This adds new BISON and RE2C utility modules on top of the find modules to have common configuration at one place. - Zend patching improved a bit - More common naming for lexers and parsers used in filenames: "grammar" - ...
The --conditions option is available since re2c 1.1.
Find modules are not meant to provide functions. This is an edge bad practice learned from some existing modules out there for convenience. Find modules should ideally only deal with finding packages and providing the imported targets. Ideally, how the package is used should be done in some wrapper module, which provides these functions. Here, the php_bison() and php_re2c(). Also, downloading is moved to these modules for now.

This simplifies downloading, configuring etc. The Bison downloading and configuring for now works only for GNU Bison. Should be improved further.
