feat(pack): vim.pack.get() gets VCS info #35631

Problem:
Force resolve `spec.version` overrides the information about whether
a user supplied `version` or not. Knowing it might be useful in some use
cases (like comparing to previously set `spec` to detect if it has
changed).

Solution:
Do not resolve `spec.version`. This also improves speed when triggering
events and calling `get()`.
- Place default branch first when listing all branches.
- Use correct terminology in `get_hash` helper.
- Do not return `{ '' }` if there are no tags.

Problem:
There is no way to get more information about installed plugins, like
current revision or default branch (necessary if resolving default
`spec.version` manually). As computing Git data migth take some time,
also allow `get()` to limit output to only necessary set of plugins.

Solution:
- introduce arguments to `get(names, opts)`, which follows other
  `vim.pack` functions. Plugin extra info is returned by default and
  should be opt-out via `opts.info = false`.
  - Examples:
    - Get current revision: `get({ 'plug-name' })[1].rev`
    - Get default branch: `get({ 'plug_name' })[1].branches[1]`
- `update()` and `del()` act on plugins in the same order their names
  are supplied. This is less surprising.
- default `opts.info` to `true` since this simplifies logic for the
  common user, while still leaving the door open for a faster `get()` if
  needed.
