Added FPDFAnnot_GetAnnotIndex() to get the index of an annotation. This
is useful if linked annotations are renedered together - then we need to
know which ones in the annotation list we need to skip.

Currently these use -1 as a special value to indicate not set. This
creates the same issues that FX_STRNPOS created for converting
FX_STRSIZE to size_t, so this code has been rewritten.

This CL creates a global font loader for use in XFA tests. This is
needed because the CFGAS_FontMangaer takes a linearly increasing amount
of time to load fonts each time it's loaded. This can get excessively
slow for test suites which run a lot of tests.

The various string classes, CFX_ByteString, CFX_ByteStringC,
CFX_WideString, and CFX_WideStringC, have many conditionals that are
effectively determining if a value is a valid index or length. This CL
refactors the logic into one place per class, so it only needs to be
changed once if its behaviour needs to change. It also make the some
of the methods stricter on the inputs they will accept.

The crash was caused by a dangling pointer in CPWL_ListCtrl to
the font map owned by CFF_TextObject. The order of events was:
1. ~CFFL_ListBox runs and calls parent destructor ~CFFL_TextObject.
2. ~CFFL_TextObject runs and deletes its member m_pFontMap. m_FontMap
was referenced by CPWL_ListCtrl which is now dangling.
3. ~CFFL_TextObject calls parent destructor ~CFFL_FormFiller.
4. ~CFFL_FormFiller calls DestroyWindows().
5. CFFL_FormFiller::DestroyWindows() deletes widgets, among them
CPWL_ListBox.
6. ~CPWL_ListBox deletes its member CPWL_ListCtrl.
7. ~CPWL_ListCtrl sees a dangling pointer to the map and crashes.
Making the DestroyWindows() call earlier in the destructor of
CFFL_TextObject, we execute steps 5-7 before freeing m_pFontMap.
An extra DestroyWindows() is still made in ~CFFL_FormFiller, but
it is then non-op if the derived CFFL_TextObject already called it.

The Find and ReverseFind methods for WideString, WideStringC,
ByteString, and ByteStringC have been converted from returning a raw
FX_STRSIZE, to returning Optional<FX_STRSIZE>, so that success/failure
can be indicated without using FX_STRNPOS.
This allows for removing FX_STRNPOS and by association makes the
conversion of FX_STRSIZE to size_t easier, since it forces checking
the return value of Find to be explictly done as well as taking the
error value out of the range of FX_STRSIZE.
New Contains methods have been added for cases where the success or
failure is all the call site to Find cared about, and the actual
position was ignored.
