Disable some optional dependencies of libtiff and freetype (#18)

Summary:
**Summary**

1. Disabling lzma, jbig, webp, and zstd
   Some the dependencies of libtiff cause build errors, cf. issues
     * #9
     * #15

   Since these dependencies are not absolutely required for Ocean, let's disable them for now.
2. Disabling harfbuzz
   On Macs (Intel-based), when `libharfbuzz*.a` exists in a system-level directory, CMake currently selects that version and not the version that comes with Ocean.

   This causes iOS builds to fail because CMake doesn't seems to notice that's intended for a different platform.

   To work-around this problem, this diff disables the build and use of harfbuzz altogether.

   Also, if harfbuzz is not absolutely required by freetype (or Ocean), we should probably remove it completely to reduce build times and complexity.

**Testing**

Confirm that the build of the third-party libraries and Ocean no longer fails because of missing `JBIG::JBIG` or similar

https://github.com/facebookresearch/ocean/blob/main/building_for_macos.md
https://github.com/facebookresearch/ocean/blob/main/building_for_ios.md

Builds fine on Macs (for macOS and iOS). Testing on Windows, Linux, and Android is still required.
