LibUnicode: Introduce a Unicode library for interacting with UCD files The Unicode standard publishes the Unicode Character Database (UCD) with information about every code point, such as each code point's upper case mapping. LibUnicode exists to download and parse UCD files at build time and to provide accessors to that data. As a start, LibUnicode includes upper- and lower-case code point converters.

LibUnicode: Download and parse the special casing UCD file This adds a SpecialCasing structure to the generated UnicodeData.h/cpp files. This structure contains casing rules for code points which have non-1-to-1 upper-to-lower case code point mappings. Further, these rules may be limited to specific locales or other context.

LibUnicode: Make unicode data generation logic more relocatable The previous logic had several checks for Lagom directories and subdirectories. All we really want to do for these header checks is make sure that the files end up in an included folder prefixed with LibUnicode. We also don't need to hard code the path to the generator, the $<TARGET_FILES> generator expression can create the path for us.

Meta: Add LibUnicode (and its tests) to Lagom This is primarily to allow using LibUnicode within LibJS and its REPL. Note: this seems to be the first time that a Lagom dependency requires generated source files. For this to work, some of Lagom's CMakeLists.txt commands needed to be re-organized to include the CMake files that fetch and parse UnicodeData.txt. The paths required to invoke the generator also differ depending on what is currently building (SerenityOS vs. Lagom as part of the Serenity build vs. a standalone Lagom build).
