The code to validate the number of parameters happens inside each particular
method, rather than prior to method dispatch. As such, there's no point in
having this number take up space in the table.
Add some test to cover at least some of the per-method validations, and
update error messages to be more useful.

The red-flag here is the explicit invocation of things like
params[1].operator CFX_WideString()
rather than
static_cast<CFX_WideString>(params[1])
to invoke the conversion. Turns out the above won't compile due to
ambiguity given the number of implicit constructors for widestrings.
CJS_Value has both constructors and assignment operators for the
primitive types, which means that conversions can take place
unexpectedly in both directions, a second red flag.
We don't want the compiler invoking these at will since it may hide
bugs. In fact, when they are removed, three such places were
discovered.
Also rename ToJSValue to ToV8Value to match the other ToV8xxxxx
functions added.

Move some typedefs for v8 types into fxjs_v8.h wrapper to
avoid circular inclusions. Also delete JS_Module.h, as no
other file includes it.

This provides no benefit, and reduces transparency.
Along the way:
Kill off some unused/commented-out code.
Return void where a bool return doesn't make sense.
Remove a pointless template type.
Remove now unused constants and types.

This implements the previously unimplemented JS_Error() function.
Along the way:
- fix some IWYU when the include order in global.cpp was perturbed.
- remove some uses of JS_ErrorString, to increase transparency.
- use vp.IsSetting() in place of !vp.IsGetting() for clarity.
- specify an error string on several error return paths.
- add an error string for writing readonly properties.
- rename an error string constant to reflect the actual message.
- replace calls to variadic Format() with a function doing string appends.
- remove unused JS_GetClassName()

Re-work of original CL at:
https://codereview.chromium.org/933043002/
Much of the IFXJS interface appears completely unused, so
Kill off unused IFXJS interface methods. The code itself
appears incomplete against all of the objects present
in the paths that actually do register objects with JS.

Continuation of effort now that a test case is present on origin/master.

This allows us to step through the JS bindings code with the
debugger, which I could not do (but wanted to) the other day.
In the process, get rid of some else after returns, and one
unreachable code path.
I also get rid of some tracing macros that we would never
use for the sake of clarity, and some plain unused
definitions.

This is a purely mechanical change, no new functionality.
- Expand some macros which were merely a short-cut to save
typing but reduced transparency.
- Put GET_VALUE_TYPE() implementation into a .cpp file.

QeTable is a 752 byte array that was defined in a header file. This
caused it to be instantiated by the VC++ compiler 12 times, wasting
8,272 bytes of space in the data segment. Because 'const' implies
'static' this did not cause any duplicate symbol errors.
JSCONST_n*HASH are a set of eight variables that are defined in a header
file. This causes them to be replicated 15 times. The variables
themselves are tiny but they are dynamically initialized and this
dynamic initialization code is replicated 15 times.
When tested on pdfium_test.exe the effect of this change is to:
Reduce the .text (code) segment by 3,616 bytes.
Reduce the .rdata section by 8,656 bytes.
Reduce the total binary file size by 13312 bytes.
These are the worst offenders for pdf.dll as shown in:
https://drive.google.com/open?id=1BvubxoA2SU_2e4T5cq7jHTjc1TlT0qOndpIfX3DMeA8&authuser=0
This will also drastically simplify the list of work to be done
for bug 441899 (getting rid of initializers).

FX_ArraySize macro.
pdfium has numerous places where the number of elements in an array is
calculated with expressions like:
sizeof(cFormats)/sizeof(FX_LPCWSTR)
This is suboptimal because it is verbose, it is easy to get wrong, and
it cannot be determined through casual inspection whether the code is
correct. It will give incorrect results if cFormats is a pointer instead
of an array and it will give incorrect results if FX_LPCWSTR is not the
type of the array elements.
The FX_WSTRC macro in fx_string.h which I fixed was particularly scary
because it would silently misbehave if passed a pointer.
The FX_ArraySize macro which I have added and started using (taken from
arraysize in v8's macros.h) is easier to use and will always give correct
results. If passed a pointer it will fail to compile.
For this change I only fixed instances of sizeof(FX_LPCWSTR). There
appear to be about 150 other places in the pdfium code that could
benefit from using FX_ArraySize.

Since casts to FX_LPCWSTR have been shown to hide bugs I tried removing
more of them, targeting those places where a cast was used to force a
conversion from CFX_WideString to FX_LPCWSTR, replacing these casts with
calls to the newly added .c_str() function. This revealed two places
where the cast was hiding a bug -- where ->c_str() was required instead!
This removes ~33 FX_LPCWSTR casts and there are ~31 left, many of which
will go away in some future change.
Also includes this change:
Removing unnecessary casts from wchar_t* to wchar_t*, by various names.

Remove casts that merely cast from wchar_t* to wchar_t*. Sometimes the
types or casts are FX_LPCWSTR but the idea is the same. Excess casts
can (and have) hidden bugs so removing these may prevent future problems.

MSVC lexes L#macro_arg as a single wide string literal token, but
Clang and other C/C++ compliant lexers do not. There was already
a workaround to use implicit string concatenation for GCC, but there's
a simpler solution of token pasting the L onto the stringized macro
argument with 'L###macro_arg'. This works with Clang, GCC, and MSVC.
