build: copy each treesitter parser library individually #20797

Copying each .so file one by one, rather than the entire parser
directory, allows newer .so files to overwrite older .so files with the
same name. This is useful when bumping a parser version and rebuilding
neovim without needing to run `make distclean` beforehand.
