feat(utils/cookie): Ability to set a priority to cookies in setCookie options

[Beyondo]

Hono's setCookie did not have Priority and I recently needed that option so I forked hono and added it. Nothing's serious been changed—succesfully tested locally.

It may be necessary to write a simple test on this.

Hi @Beyondo

Thank you for the PR. Looks good. I'll merge this later and induce this change in the next patch release.
