This Cl consolidates the code to load maps and codecs into the
CPDF_ModuleMgr class instead of putting it directly into fpdfview.

In AGG, len is of type coord_type, which we have as int16_t, but we can add to
it large values, causing it to become negative. Stop the rendering when that
occurs.

bpno_plus_one is used as a parameter bpno for a bunch of methods that calculate
1 << bpno. Thus, use a reduced value when it's large enough to cause undefined
shift. bpno_plus_one itself remains unchanged so that the number of calls
remains the same

When decoding the CPDF_HintTable we read the dwDeltaGroupLen value out
of the input stream which is a 16bit number. That value is then passed
in to read a uint32_t of the object number. If we have a group length of
> 32 bits we'll cause an undefined shift when we attempt to shift right
more then 32 bits.
This Cl bails out early if the dwDeltaGroupLen value is > 32 in order to
stop the undefined shifts.

In a way similar to the existing USE_SYSTEM_LIBJPEG. The default is of
course still the DEPS-based zlib checkout.
Changes in v2:
1) Since Chromium doesn't have //third_party:zlib (AKA a "zlib" target in
//third_party/BUILD.GN) all the targets that depended on //third_party:zlib now
depend on third_party:zlib, which always points to PDFium's
third_party/BUILD.GN. The targets that depended on //third_party:zlib in
third_party/BUILD.GN just depend on :zlib instead.
2) Move the zlib bits out of !build_with_chromium block.
