lib: use validateArray for array arguments

Three call sites still duplicated the ArrayIsArray check that
validateArray already performs. Both files were already importing other
validators next to these checks. The error code, argument name and
expected type are unchanged, so the thrown error stays identical.

The ArrayIsArray primordial is no longer used in histogram.js and is
dropped from its destructuring; blocklist.js still uses it elsewhere.

The existing tests only asserted the error code, so assertions covering
the full error message are added for all three call sites. They pass
both before and after this change.
