a652281ed6 [subset] Fix fuzzer timeout. 
Fixes https://oss-fuzz.com/testcase-detail/5979721620652032. Timeout was caused by degenerate map insert behaviour due to poor integer hash function. Presize the map to avoid it. Also fixes collect_mapping() for cmap format 13.

42aba5ff30 harfbuzz-config.cmake.in: Support Windows usage 
Apply the appropriate library prefix/suffix by whether we are building
as a statib build in Meson, or by using
${CMAKE_[SHARED|IMPORT]_LIBRARY_PREFIX} and
${CMAKE_[SHARED|IMPORT]_LIRBARY_SUFFIX} as appropriate according to
the target platform for shared builds.

[subset] Use vector instead of map for glyph bounds (#4232) 
* [subset] Use vector instead of map for glyph bounds

Is faster.

Part of https://github.com/harfbuzz/harfbuzz/issues/4231

* [subset] initialize bounds_vec value to 0xFFFFFFFF

Some non-EMPTY glyph might have 0 bounds width/height
