It's been troubling for some time that an IFX_FileStream might
actually be an in-memory buffer with no backing file.

core/fxge/android files all have if _FX_OS_ == _FX_ANDROID_. Instead,
put the files inside if (is_android) on Build.gn. Also, the skia file
is already under if (pdf_use_skia), so the if defined(_SKIA_SUPPORT_)
can be removed.

This CL implemented a better version of CWeightTable::GetPixelWeightSize(), which will calculate the size of array PixelWeight.m_Weights correctly to prevent potential heap buffer overflow conditions.

Notice that this is just making it analoguous to how it works when the
font is positive: the b and d components are reversed. Currently, when
the font is negative, only the a component is reversed. The c one needs
to be reversed as well.

Instead of relying on ' ' to determine whether the CFX_Bytestring
is added on one place or another, use another vector. When trying
to match fonts from the fontmapper, compare with both vectors.

The buffer PixelWeight.m_Weights was allocated by calling FX_TryAlloc(uint8_t, m_dwWeightTablesSize),
but PixelWeight.m_Weights was an int array. Thus bounds check such as |if (idx >= m_dwWeightTablesSize)|
in function CWeightTable::Calc() and |idx < m_dwWeightTablesSize ? &pWeight->m_Weights[idx] : nullptr|
in function CWeightTable::GetValueFromPixelWeight() were insufficient.
This CL strengthens bounds check for accessing int type array PixelWeight.m_Weights.

PWL_FontMap does not need its own charset definitions. fx_edit.h does
not need to define DEFAULT_CHARSET. XFA have their own definitions.
They look different in that most are MAC or MSWin charset definitions.
So they are left untouched. public/fpdf_sysfontinfo.h duplicate ones
were left untouched due to being in public folder.

CFX_FaceCache::LookUpGlyphBitMap should remember its unsuccessful glyph
bitmap calculations. This is especially important if there are a lot of
repeated requests for the same glyph with large bitmaps (which means
long calculations in freetype). With this CL, the pdf in the bug below
will be rendered quickly.

A few issues are fixed:
--Change variable |m_bLogic| in CFX_Font to |m_bShallowCopy| to
reflect its meaning better;
--For a shallow copy of font, we must guarantee that the copied font
will not be deleted until the shallow copy is deleted. So need to
increase the src font's refcount when copying it;
--The stream |m_pOwnedStream| needs to have matched new/delete
These errors need to be fixed before we can properly delete all the
fonts to address the leaks.

The FX layer is spying on its private data, so make the job
of ref-counting it live in FX as well, instead of up a layer
at pdfapi.
Pre-cursor to making this private and passing the graph
state itself everywhere.

Allows CFX_CountRefs to behave more like pointers.
Rename SetNull() to Clear() for consistency with other ptrs.
Change GetPrivateCopy() into MakePrivateCopy() with no return,
since the -> operators are clearer than getting an object pointer.
