refactor(net): removes direct ui invocation from filemgr thread
<!-- Please describe your changes on the following line: -->
- relates to https://github.com/servo/servo/issues/20428.
This PR tries to refactor `net::filemanager_thread` implementation, removes direct ui-related code invocation but ask constellation. I believe overall organization might need to be refactored still as I took my own liberty to wire up dots and dots between components, which could be non-recommended practices.
Probably point of review / need to be updated are
1. Communication between components
Currently it's wired as like below:
```
+----------------+ +---------------+ +---------+
| | constellationMsg | | embedderMsg | |
| filemgr_thread +------------------->+ constellation +------------->+ browser |
| | | | | |
+-----+----------+ +---------------+ +----+----+
^ |
+-------------------------------------------------------------------+
filelist: Vec(String)
```
- is this feasible approach?
- does organization of message / fn (where to put consteallation / embedder msg & fns) are legit?
2. Removal of `filemanger_thread::UIProvider`
- As filemanager_thread no longer need to aware actual ui, this PR removes `UIProvider` completely and let invoke tinyfiledialog directly in message listener. Maybe UIProvider itself still being needed?
3. Overall fn organization
- To reduce duplicated code it takes single msg with boolean flag to distinguish selecting multiple files, may feasible / or better to create explicit paths between two.
4. Invoking tfd in a separate thread
- This was mainly to align behavior to previous implentation, where tfd was invoked inside of filemanager_thread so does not block main. It may possibly just let block instead.
and of course, a lot of other codes need to follow better practices.

This is the basic structure of the stuff. Following patches will fill
the gap between Gecko and Servo on value generating, and finally hook
it into InspectorUtils.

The only difference in the final result is "all" shorthand, for which
the original result is wrong because "all" shorthand doesn't accept any
value other than the CSS-wide keywords.

I didn't bother not shifting there. We need to load the whole thing and shift
for at least one of cascade level / shadow cascade order.
Callers of level() other than for_rule_tree are non-existent in release builds,
so we'd be doing the shift anyway. I can implement the same thing for
shadow_cascade_order too, but I don't think that optimization is measurable in
any way, either, the compiler should make the decision.
And just in case, the simpler version actually generated less instructions in:
https://play.rust-lang.org/?gist=ceadb0d3cbce4eeca76e4d9ab9a1c744&version=nightly
with the simple thing.

No cleaner ideas right now that carrying that counter around... Maybe a custom
type may be cleaner?
This makes ApplicableDeclarationBlock a bit bigger. I could probably try to make
the counter a 4 / 5-bit number or something and pack the counter there in the
SourceOrderAndCascadeLevel somehow...
But doesn't seem really worth the churn, and can be done as a followup in any
case. Let me know if you want to block on that.

Note that we also drop the dead optional aReusableSheets argument from
the async parsing path, since it was always null.

Make gleam optional for compositor, switch various names from glutin to winit
<!-- Please describe your changes on the following line: -->
The PR goes an extra step towards discriminating GL to a level of an optional dependency. This would ease up the transition to gfx-hal when the time calls for it, and upstreams some of the patches we've been using locally, cleans up some of the old cruft along the way.

This is necessary because we can't create GeckoStyleSheets off-main-thread,
