Make the use of gold linker configurable
Currently, ld.gold is always used for linking if found on the
system. There are some cases however when one may want to opt out
from using it. This patch adds the boolean field `rustc-with-gold`
to the `[tools]` section of `.servobuild`, which if set false,
disables the use of ld.gold.

In #7348 `os.walk` was replaced with `os.listdir`. The latter is not
recursive, which results in only the root directory files getting linted
The changes to `ignored_files` are needed because calling `os.walk(".")`
results in `./` getting prefixed before each path

I thought it might be helpful to say which files aren't used in `basic.list`.
`./mach test-tidy` is a second or two slower on my laptop.
Not sure if this counts as a warning or an error that should return 1.
Not sure whether unused file output should go before or after the line specific errors.

Prior to this commit:
* Our Python dependency story was a bit of a mess. We had complete
Python packages (wheels and directories) living in-tree, despite
not having any changes from upstream. This is particularly bad because
`setup.py` never gets run on these packages which could (sometimes
silently) unintended breakage.
* Python virtual environments (virtualenv) were only utilized for
testing web-platform tests
After this commit:
* A single virtualenv (`python/_virtualenv`) is activated upon *every*
call to mach
* A requirements file (`python/requirements.txt`) is added to describe
the dependencies needed by Python modules in `python/`. The child
commit immediately following this will remove all the dependencies
no longer needed in-tree (for the sake of keeping this commit
readable).
