Fix build on MSVC >= 2012
...
Use the DEFINE_ENUM_FLAG_OPERATORS macro in winnt.h on Visual Studio,
which defines the bitwise operators for the enumerations that we want to
mark as hb_mark_as_flags_t, which will take care of the situation on newer
Visual Studio (>= 2012), where the build breaks with C2057 errors as the
underlying types of the enumerations is not clear to the compiler when we
do a bitwise op within the declaration of the enumerations themselves.
Also disable the C4200 (nonstandard extension used : zero-sized array in
struct/union) and C4800 ('type' : forcing value to bool 'true' or 'false'
(performance warning)) warnings as the C4200 is the intended scenario and
C4800 is harmless but is so far an unavoidable side effect of using
DEFINE_ENUM_FLAG_OPERATORS.

hb-ot-shape-complex-arabic.cc: Fix build on Visual Studio

Visual Studio does not like declaring a enum variable within a for
statement, so fix the build by declaring the enum before doing the for
loop.

MSVC builds: Add fallback implementation for pre-2013 MSVC
...
Pre-2013 MSVC does not have scalbn() and scalbnf(), which are used in the
utility programs. Add fallback implementations for these, which can be
used when necessary.

util: Fix build on Visual Studio
...
Use the fallback implementation for lround() only on pre-2013 Visual
Studio, and ensure we are clear about the types of the parameters for
lround() and scalbnf(), since Visual Studio can be quite picky on
ambiguous parameter types. Also, use g_ascii_strcasecmp() rather than
strcasecmp() as we are already using GLib for this code and we are
assured that g_ascii_strcasemp() is available.
For scalbnf() on pre-2013 Visaul Studio, a fallback implementation is
needed, but use another forced-included header for those compilers, which
will be added later.
Also use (char)27 on Visual Studio builds as '\e' is not a recognized
escape sequence, which will do the same thing.
