ANDROID: GKI: enable CONFIG_DEBUG_INFO_COMPRESSED_ZSTD=y

DWARF debug info is the largest contributor to the file size of vmlinux.  By
compressing the debug info via ZSTD, we can significantly reduce the binary
image size for little to no meaningful change in build time (and slightly more
time spent to compress this data when actually consumed; tools need to support
compressed debug info).

$ du -h vmlinux_compressed vmlinux_uncompressed

299M	vmlinux_uncompressed
