runtime: avoid clearing memory during byte slice allocation in gobytes
Avoid using make in gobytes which clears the byte slice backing
array unnecessarily since the content is overwritten immediately again.
Check that the user provided length is positive and below the maximum
allowed allocation size explicitly in gobytes as this was done in makeslice
before this change.
Fixes #23634
