zlib: validate pledgedSrcSize as a safe integer

pledgedSrcSize represents an exact byte count. Reject values that are
not non-negative safe integers instead of silently ignoring or coercing
them through IntegerValue().
Apply the same validation to zlib/iter and retain a native validation
check for internal callers.
