Download extra stdlib only when required: #9557
Split [`ensure_bootstrap`](https://github.com/danlrobertson/servo/blob/i9557/python/servo/command_base.py#L397-L422) into two phases including a phase checking the compiler, and a phase checking for target libraries. E.g.
```
# should download the stdlib for "i686-unknown-linux-gnu", "arm-linux-androideabi"
# and the hosts target
./mach build -d --target i686-unknown-linux-gnu --android
# should only download the stdlib for the hosts target
./mach build -d
```
Let me know if I missed anything! There are a few parts of this patch in its current state that I'm not a huge fan of, but I couldn't think of a better way in the moment.
Still new to working on servo, so any comments or critiques are welcome!

Integrate compiletest_rs
This PR integrates `compiletest_rs` as suggested in #5646. I created a new `tests/compiletest` directory which contains separate crates for the tests.
Currently this PR includes `compile-fail` tests for some lints (acutally all except inheritance_integrity, beacuse I'm not sure how to include the dom stuff in a way the `#[dom_struct]` works).
I gathered that there should be more crates for which compiletests make sense and would appreciate any pointers to relevant crates.

Fix unicode PATH the same way as mozilla-central does it for windows.
Also append extra PATHs instead of prepending, for some reason that broke ./mach run
Win32 support
r? @frewsxcv for python stuff
r? @pcwalton for the "remove usage of Gaol" stuff for Win32
r? anybody else for misc cargo.lock updates, etc.
This replaces #7878.
This works best with https://github.com/servo/mozjs/pull/71, too, to enable static linking, but can be run without (via some PATH hackery).
The instructions are here, and will be added to a .md file in the repo once the mozjs changes also land:
https://hackpad.com/Servo-on-Windows-C1LPcI2bP25
I'd like to get these changes landed because I've been rebasing them for months, they're otherwise quite stable, and don't affect our other platforms and targets.

- Add SERVO_USE_NIGHTLY_RUST env var to use the latest rust/cargo nightly snapshot
- Fix up looking for cargo binary (in cargo/bin/cargo, not bin/cargo)
- Fix up win32 executable checking (use .exe suffix)
- fix up win32 PATH handling (subprocess must use shell=True for PATH change to be honored)
Add Partial Implementation of style DOM traits for Gecko, and some basic glue to let Gecko call into Servo
The wrapper stuff is partially-complete, modulo some unimplemented methods. The glue code is just a toy for now. Regardless, I think it's worth getting some of this stuff in-tree to minimize breakage.

Add 'test-tidy-faster' command to ./mach
For issue #9088, this adds a `--changes` option to `./mach test-tidy`. If this option is set, `tidy.py` will only check files that have been modified since `FETCH_HEAD`.

Make "mach run" use --android by default when enabled in .servobuild
When `.servobuild` has `android = true`, the `mach run` command should default to running on Android.

mach run --debug: Try using rust-gdb/rust-lldb if available
If the selected debugger (requested explicitly or detected by mozdebug)
is gdb or lldb, use rust-gdb or rust-lldb instead, if it's available in
the path and appears to be working.
(This should usually be the case when using the default debugger on
GNU/Linux or MacOS, as rust-gdb or rust-lldb is provided by the Rust
snapshot in use.)
Note: I cobbled this together without *any* previous Python experience -- so if it violates three dozen rules, and only works by luck on my own system during a favourable moon phase, don't hesitate to suggest improvements :-)
