This patch:
* Makes StyleStructID an enum class, and moves it to the mozilla namespaces.
* Introduces StyleStructConstants with some constants scattered through the
codebase.
* Makes the computed style bits an enum class, and splits mPseudoType and mBits
into their own members, since we were using a uint64_t when we have only a
couple flags and CSSPseudoElementType is a byte. We statically assert that
the number of style structs is less or equal to 32.
* Makes mPseudoTag, mPseudoType and mBits const, since we don't want them to be
mutated from C++, and we still need a few more refactorings (mostly getting
rid of FinishStyle) to avoid mutating ComputedStyle instead.

nsStyleStructList.h was initially made generated in bug 873368 to avoid
manually maintaining boilerplate for if-dispatch, while the if-dispatch
was replaced by jump table in bug 1171842, so the boilerplate went away.
However, in bug 1122781 (before bug 1171842), boilerplate for dependency
check, so it still needs to be generated.
The dependency table is removed in the previous patch, so we no longer
have any boilerplate in the style struct list, and thus it doesn't need
to be generated anymore.

This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py
For every file that is modified in this patch, the changes are as follows:
(1) The patch changes the file to use the exact C++ mode lines from the
Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line
(2) The patch deletes any blank lines between the mode line & the MPL
boilerplate comment.
(3) If the file previously had the mode lines and MPL boilerplate in a
single contiguous C++ comment, then the patch splits them into
separate C++ comments, to match the boilerplate in the coding style.

This patch adds a mechanism to check struct computation against a known set of non-cyclic dependencies.
The checks are only done when we get a struct on a context during computation of a struct on the same context.

This bumps up nsStyleContext::mBits to a uint64_t so that it can fit
another style struct. If we're going to need to keep at least 27 style
structs, it might be better to split mBits up into two uint32_ts: one
for the flags and one for the style struct bits.
