rts: use XXH3_64bits hash on all 64-bit platforms

This commit enables XXH3_64bits hash to be used on all 64-bit
platforms. Previously it was only enabled on x86_64, so platforms like
aarch64 silently falls back to using XXH32 which degrades the hashing
function quality.

rts: define XXH_INLINE_ALL

This commit cleans up how we include the xxhash.h header and only
define XXH_INLINE_ALL, which is sufficient to inline the xxHash
functions without symbol collision.
