Add Brotli dependency and required checks.
Brotli is required for decompressing WOFF2 font directory streams. The library is thus being added as an optional dependency for FreeType. * builds/unix/configure.raw: Add checks for `libbrotlidec'. * devel/ftoption.h, include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_BROTLI): New macro.
