This patch changes how a VarCache pref works when deleted (in some cases) --
the VarCache variable keeps its existing value instead of being reset to a
pre-specified default.
In bug 1570212 I have made sure that no VarCache prefs exhibit this behaviour
in practice any more, so this change should not affect functionality. There is
an assertion that checks this.
The next patch will take advantage of this change by removing the need to
store the pre-specified defaults, which will save memory.

The patch:
- changes `privacy.resistFingerprinting.target_video_res` to a static pref;
- changes `privacy.resistFingerprinting.video_frames_per_sec` and
`privacy.resistFingerprinting.video_dropped_ratio` to code constants;
- removes the unused `RFP_TIMER_VALUE_DEFAULT` and `RFP_JITTER_VALUE_DEFAULT`
constants.

security-prefs.js is #included into greprefs.js, but there's no good reason for
it to be separate from all.js. Having it separate makes it easier to overlook,
and all.js has a bunch of `security.*` prefs in it anyway.
This patch inlines it into all.js. It inlines it at the start of the file to
minimize the risk of the change, so that the prefs end up in greprefs.js in the
same order as before.

It's much nicer.
One nice thing about this is that the new code is subject to the existing
threadedness checking, which identified that several of these should be atomic
because they're accessed off the main thread.

This patch introduces a new Rust crate called `static_prefs`.
It also changes generate_static_pref_list.py to generate two new files.
- StaticPrefsCGetters.cpp: contains C getters, which are just wrappers around
the C++ getters. This is included into Preferences.cpp.
- static_prefs.rs: contains declarations for the C getters, plus the `pref!`
macro which provides nice syntax for calling the C getters. This is included
into static_prefs/src/lib.rs.
The new code is only generated for prefs marked with the new `rust` field in
the YAML. It's opt-in because there's no point generating additional code for
900+ static prefs when only about 20 are currently used from Rust.
This patch only marks a single pref (`browser.display.document_color_use`) with
`rust: true`. That pref isn't accessed from Rust code in this patch, but it's
necessary because the generated Rust code is invalid if there are zero
Rust-accessed prefs. (The next patch will access that pref and others from Rust
code.

generate_static_pref_list currently has two functions:
- generate_header(): this checks the YAML and generates most of the code.
- emit_header(): this does a bit of additional code generation and writes the
code to file.
This patch gives it a cleaner structure:
- check_pref_list(): this checks the YAML.
- generate_code(): this generates all the code. (It calls check_pref_list()
first.)
- emit_code(): this just writes the code to file.
The patch also improves the testing in test_generate_static_pref_list.py,
so that it checks the full contents of all generated files.
All these improvements will help with the next patch, which adds two additional
generated files.
The patch also fixes a couple of minor errors in the comment at the top of
StaticPrefList.yaml.
