moved clang-format to tools directory

[p01arst0rm]

Moved the clang-format tool into the /tools directory.

It's a third-party component, why (and also why #2098)? For the ease of managing licenses and updating, we don't put, for instance, the Vulkan headers in src/xenia/ui/vulkan.

I accepted #2098 because vswhere is a binary, I don't think we need to move clang-format.

Thank you

using a single directory to contain all third party code is a legacy buildsystem design technique. placing tools in directories that align with their actual project use is easier;- it also allows you to ignore entire directories to exclude them from packages. newer project layouts place documentation in /doc tools in /tools data in /data and so on

There is also some code within third_party which is actually xenia project code, the third_party label appears to be entirely arbitrary .
