Compress OpenCL kernel files using zlib for Android
Kernel files are embedded into the binary as the default option when
building which leads to binary size bloating.
Add `compress_kernels` option and utilize zlib for further compressing
the text kernel files and reduce the overall binary size. We use a
base64 encoding/decoding to ensure that the strings can be easily
embedded. This adds to the binary size but still the overall reduction
is significant.
Maximum compression level 9 is used.
Option is currently restricted to Android builds as android toolchain
provides a zlib library.
Initial experimentations indicate a binary size reduction of 50%
