core: allow building against system zlib
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.
