This is a second fix for the issue discussed in #20411. My first PR (#21279) didn't fix the bug in all cases, sorry.

If a YAML string has too many spaces in the value, it can trigger a `PREG_BACKTRACK_LIMIT_ERROR` error in the Yaml parser.

There should be no behavioural change other than the bug fix

I have included a test which fails before this fix and passes after this fix.

I have also added checks that detect other PCRE internal errors and throw a more descriptive exception. Before this patch, the YAML engine would often give incorrect results, rather than throwing, on a PCRE `PREG_BACKTRACK_LIMIT_ERROR` error.
