cmake: work around xxhash 'inlining failed' errors in debug builds

rgw enables the XXH_INLINE_ALL define, but this causes debug builds to
fail with errors like "inlining failed in call to ‘always_inline’"

for build types Debug and RelWithDebInfo, add extra define
XXH_NO_INLINE_HINTS to remove the always_inline hints causing this error
