errors in the shared library build on Windows.
* Fix -DAVIF_GTEST=SYSTEM
* Fix infe_type and codec_config_type wrongly read as byte-

* Add experimental API for reading and writing gain maps in
AVIF files.
* If enabled at compile time, add `gainMap` field to
`avifImage`,
* add `qualityGainMap` field to `avifEncoder`, add
