LOG: [clang-doc][cmake] Copy assets to build directory (#95187)

While we copy the asset files, like index.js, into the correct location
in the install step, tests do not have access to those resources in the
build directory.

This patch copies the contents of the clang-doc/assets directory into
the build folder, so that they can be used in testing.
