There are two ways I see to do this:

1. "${CMAKE_COMMAND}" tar https://cmake.org/cmake/help/latest/manual/cmake.1.html#run-a-command-line-tool
2. file(EXTRACT_ARCHIVE) https://cmake.org/cmake/help/latest/command/file.html?highlight=file#archive-extract

This affects the way we download the following data sets at configure time:

• UCD (Unicode Character Database)
• CLDR (Unicode Common Locale Data Repository)
• PCI ID Database
• USB ID Database
• Wasm spec tests

After these datasets are extracted using one of the above methods, we can remove at least unzip from the build requirements. tar is still currently required for the Toolchain builds, but there's a chance we could do those using CMake too 👀
