From: Jeremy Linton <[email protected]> [redhat] configs: Compress UEFI/PE kernels with zstd
Zstd compressed kernels consume less disk space and decompress faster than gziped ones. For example, kernel 6.12rc3 aarch64's on disk size is ~22% smaller and boots ~16% faster on a RPi4. Since this was already on for some x86 flavors, lets propagate the setting to all appropriate UEFI architectures (x86, aarch64, riscv) and kernel flavors for those architectures. PPC and S390 should not be affected except to remove a ppc UNCOMPRESSED vs GZIPed conflict that was being corrected by the kconfig process.
