playground: prevent caching memory-related runtime errors

The existing implementation only prevents code caching if the code has
certain compile-time errors. Code with deterministic runtime errors, such as
out of memory errors, are being cached. This causes errors to be
returned in the Go Tour if a different user's run caused an error.
The cache had to be manually cleared in order to clean out the bad run.
This change prevents code that threw an "out of memory" or a "cannot
allocate memory" error from being cached.

Fixes golang/go#26926
