Wez Furlong d78cc6edb8 new: exec_domains
An ExecDomain is a variation on WslDomain with the key difference
being that you can control how to map the command that would be
executed.

The idea is that the user can define eg: a domain for a docker
container, or a domain that chooses to run every command in its
own cgroup.

The example below shows a really crappy implementation as a
demonstration:

```
local wezterm = require 'wezterm'

return {
  exec_domains = {
    -- Commands executed in the woot domain have "WOOT" echoed
    -- first and are then run via bash.
    -- `cmd` is a SpawnCommand
    wezterm.exec_domain("woot", function(cmd)
      if cmd.args then
        cmd.args = {
          "bash",
          "-c",
          "echo WOOT && " .. wezterm.shell_join_args(cmd.args)
        }
      end
      -- you must return the SpawnCommand that will be run
      return cmd
    end),
  },
  default_domain = "woot",
}
```

This commit unfortunately does more than should go into a single
commit, but I'm a bit too lazy to wrangle splitting it up.

* Reverts the nil/null stuff from #2177 and makes the
  `ExtendSelectionToMouseCursor` parameter mandatory to dodge
  a whole load of urgh around nil in table values. That is
  necessary because SpawnCommand uses optional fields and the
  userdata proxy was making that a PITA.
* Adds some shell quoting helper functions
* Adds ExecDomain itself, which is really just a way to
  to run a callback to fixup the command that will be run.
  That command is converted to a SpawnCommand for the callback
  to process in lua and return an adjusted version of it,
  then converted back to a command builder for execution.
