feat(doc): support multiple file entry (#21018)

This commit adds support for multiple entry points to `deno doc`.

Unfortunately to achieve that, I had to change the semantics of the
command to explicitly require `--filter` parameter for filtering
symbols, instead of treating second free argument as the filter argument.

`deno doc --builtin` is still supported, but cannot be mixed with
actual entrypoints.
