When calling the FXSYS_wctof method we currently pass in -1 from
AdvanceForNumber. This tells the method to calculate the string length.
This can be slow for a formcalc string with a lot of numbers.
This CL changes the call to pass in the length of remaining data in the
original string. This takes the MSAN runtime of the case in the linked
bug from ~21seconds to ~500ms. The debug runtime goes from ~2s to
~500ms.

This allows compilers targeting the MS ABI to select the correct inheritance
model for the member function pointer type XFA_ATTRIBUTE_CALLBACK using the
complete type of CJX_Object. It will allow us to enable the new Clang flag
-fcomplete-member-pointers globally.

When converting a Var statement from formcalc to JS we would neglect to
add the ; if the variable was initialized. This generated invalid JS as
we'd end up with two statements smushed together.
FormCalc:
var s = ""
Previous JS:
var s = ""s = pfm....
New JS:
var s = "";
s = pfm ...

When calling into the XFA JS engine with a request for a non-XFA JS
call which accesses the EventContext we would get a crash in XFA as we
never set the context. This CL changes the XFA code to accept the
CJS_Runtime instead of the CFXJS_Engine and then calls NewEventContext
before executing JS scripts. This will correctly setup the event context
as needed for any JS callbacks.

Removed some unused assignments and now unused variables.
Also rewrote a for loop so that its secondary condition is now in the
control block. The static analyzer was claiming it was possible for a
division by 0, though following the control path it was claiming, I am
pretty sure it should have exited early. This reorganizing of the code
makes it a bit more readable and eliminates the div by 0 warning from
the static analyzer.
Issues found with Clang Static Analyzer.

Because it returns an unique_ptr to a newly-created object.
Also rename m_pTimeMgrAdapter to m_pAdapterTimerMgr, because in
English, adjectives come first, and this is a TimerMgr obtained
from an Adatper, not an Adapter for a TimerMgr. Also change TimeMgr

When generating PDFs using the fixup script and a .in, specify them to
to use Ahem.ttf as the text font. Ahem is a font designed to reduce
flakiness in pixel tests due to font rendering differences between
platforms. Specifically the glyphs in the font are standard size black
boxes, so though the specific text content cannot be easily compared,
things like layout and high level changes to the content can still
be tested. Testing things like specific text changes should be done
via an embedder test, where the strings in the elements can be
extracted and inspected.
The font itself is is CID type 2 font, which is relatively complex to
correctly embed in a PDF due to subsetting and other features. Instead
of embedding it in the generated PDFs, which was originally attempted,
it is being supplied to pdfium_test via the --font-dir flag. This flag
overrides where the binary looks for system fonts. This works
correctly on Mac and Linux, but not on Windows, which is why that
platform remains suppressed.

This fixes two partially interrelated bugs with font loading in XFA
documents. First, it adds falling back to the builtin fonts if there
are no viable embedded or installed font for the top-level XFA font
manager. Additionally it changes the load font code path in
CXFA_FWLTheme to use the top level XFA font manager, instead of the
one that just handles the system installed fonts.
The main visible issue that this patch fixes is that currently using
--font-dir with pdfium_test on a XFA PDF can cause text to not be
displayed in widgets and/or NOTREACHED asserts. This occurs if there
isn't a needed fonts embedded in the document or in the font
directory, since currently PDFium will not correctly fall back to the
builtins.
