`build`: generate hex dump of server assets during build (#6661) * `build`: generate hex dumps of server assets on the fly * build: workaround lack of -n on gnu xxd * build: don't use xxd in cmake * build: don't call xxd from build.zig * build: more idiomatic hexing * build: don't use xxd in Makefile (od hackery instead) * build: avoid exceeding max cmd line limit in makefile hex dump * build: hex dump assets at cmake build time (not config time) 2024-04-21 17:48:53 +00:00			# CMake equivalent of `xxd -i ${INPUT} ${OUTPUT}`
