[meson] Fix dependency lookup and generate `ftconfig.h`. - zlib: If not found on the system, meson can build it as a subproject. We thus never use the (outdated) zlib support that comes with FreeType. Doing so has the additional advantage that the zlib code can be shared with other projects like GLib if both are subprojects of an application. - harfbuzz: Build as a subproject if not found on the system. - 'QUESTION: What if the compiler doesn't support `-D` but uses `/D` instead as on Windows?' Answer: Meson translate arguments for us. - visibility: Replace self-made code with meson-specific solution. * meson.build (ft2_defines): Rewrite logic to set and handle it. (process_header_command): New variable, previously called `ftoption_command`. (ftoption_command, ftconfig_command): New variables. (zlib_option): Removed. (zlib_dep): New variable. (ft2_deps): Updated. (harfbuzz_dep): Updated. (ftconfig_h_in, ftconfig_h): New variables. (ft2_sources): Updated. (ft2_lib): Updated, handle visibility. (summary): Updted. * meson_options.txt (zlib): Updated.
