Link NFD statically

Currently, the profiler will build against the git NFD, but link it as a
shared library. Since libnfd is not installed when building Tracy as a
distro package, it will end up actually depending on and running against
an older distro-provided NFD, hitting an unresolved function error due
to the newly added NFD function in git.

Other deps fetched with CPM are linked statically, avoiding this
problem.
