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.

Added a vector of pointers to CFX_Fonts in the class CPDF_Font, so that
fallback fonts may be used. In CPDF_CharPosList::Load, the glyphs for each
character are calculated. When m_Font does not support a character, a fallback
font is selected and the character is rendered using that font. This meant
adding an attribute to FXTEXT_CHARPOS so it knows which font renders it.
Also, methods in fpdf_render_text.cpp now may need to call device drawing
methods multiple times because these only support one font at a time. In
CPDF_TextRenderer::DrawNormalText and in CPDF_TextRenderer::DrawTextPath, the
device drawing method is called as few times as possible by grouping contiguous
characters rendered by the same font. In
CPDF_RenderStatus::DrawTextPathWithPattern, drawing was already done one
character at a time, but precalculating CFX_FaceCache. Now, the face cache is
precalculated for all of the fallback fonts.
The list of fallback fonts does not include tha main font. Otherwise the list
would be of raw pointers to avoid double free problems. For now, the font
Arial is used as fallback. This should fix the issue of not seeing Latin
characters displayed when bad fonts are used. However, this should be improved.
Tested manually using the file in the bug, plus a font directory containing a
font that supports Hangul but not Latin. This font is chosen as the substitute
font, but Latin characters are now being rendered.

CFX_SubstFont::m_ExtHandle is never assigned a value different from nullptr.
Similarly, IFX_SystemFontInfo::RetainFont has two implementations.
Both of these return nullptr, so this method is not needed.
