feat: allow execution ordering of coder modules

[djarbz]

How can we specify the order in which modules run?

For example, I want the Personalize module to run after my Dotfiles have been fully cloned as I have a personalization script in my dotfiles.

Both of these modules make use of coder_script resource. So that needs to support the order first.

Ok, do I need to open an issue elsewhere?

@djarbz A linked issue is created on the coder/coder repo. coder/coder#10352

@matifali could there at least be an option for an initial script to run from the main agent, like a init_script that can do some things ahead of any other scripts. Like copying some resources, that can later on be referenced?
