Add env var for local saltfs root during bootstrap
<!-- Please describe your changes on the following line: -->
This enables using the environment variable `SERVO_SALTFS_ROOT` to use a local copy of the saltfs tree for `./mach bootstrap`. The immediate use case is to add a test for `./mach bootstrap` to saltfs itself, to ensure Salt changes or refactors don't break `./mach bootstrap`.
I tested this locally in an Ubuntu Trusty VM.

Add `--dry-run` argument to `mach cargo-update`
This add ability to check which packages are outdated, also detect which updates are minor and which may contain breaking changes.

`incremental = true` can be set in the `[build]` section of `.servobuild`
to enable incremental compilation.
In `./mach build-geckolib`, which uses a stable version of the compiler,
this would cause a warning repeated for each invocation of rustc:
```
warning: the option `Z` is unstable and should only be used on the nightly
compiler, but it is currently accepted for backwards compatibility;
this will soon change, see issue #31847 for more details
```
This PR disables incremental compilation for `build-geckolib`,
regardless of `.servobuild` settings.

Sometimes clippy gets outdated by months, and its current support setup
means that each Servo component need to opt into it by depending on
the plugins crate manually, and not all components do that.
Allow running servo in software rendering mode from ./mach run
<!-- Please describe your changes on the following line: -->
This adds a flag to ./mach run to use software rendering on Linux (through the LIBGL_ALWAYS_SOFTWARE env var).

The Salt bootstrapper invokes Salt during `./mach bootstrap`
to install Servo's build dependencies.
It uses salt-call pinned to the same version of Salt as used in saltfs.
Currently, the implementation uses gitfs and reads directly from
the master branch of the saltfs repo;
in the future this should be changed when the relevant Salt states
are moved in-tree as part of Dockerization for TaskCluster.
We have not Salted our Windows machines, so the existing Windows
bootstrappers are retained. Currently this is only tested on
Ubuntu Trusty.
Salt uses various system python libraries,
including `python-apt` on Debian-based OSes to interact with apt.
`python-apt` does not seem to be installable via a requirements.txt
file, and the versions available on PyPI are far behind the versions
installed on actual Ubuntu machines.
Additionally, adding `python-apt` as an unconditional python dependency
would add bloat for users of other OSes, and lead to more churn
as additional OSes are supported.
However, as `python-apt` is already installed via apt on these machines,
we can allow Salt to instead use the module by using
`--system-site-packages` for the python virtualenv.
We also add the `-I` flag to `pip install` to ensure we have a local,
untouched copy of any other python packages used.
However, because this prints system-level Python packages in scope,
it slightly breaks isolation, so it is important to always pin
all dependencies in the requirements files.
- Default to interactive mode and remove the `--interactive` flag
- Use `--force` to skip interactivity
- Change MSVC dependency storage organization on disk: put each version
into its own folder and directly refer to the versioned folders,
providing immutability and making the installation list redundant
- Reuse `host_triple()` function to fix broken bootstrapper dispatching
- Simplify code:
- Remove or inline many unused and redudant functions and variables
- Prefer plain functions to classes
- Consolidate into fewer files, remove unnecessary bootstrapper/ dir
- Improve Python style
- Sort dependency list
Allow passing --nocapture argument to test-unit mach command
This adds the ` --nocapture` argument to the test-unit mach command.
Defaulting to false, when given it passes `-- --nocapture` to cargo test to show stdout during test-unit runs.
