MDBF-1076 - Increase jobs for clang-20 debug builder

Tests showed 2 hours for parallel = 6 during MTR:
https://buildbot.dev.mariadb.org/#/builders/535/builds/7

Quite unacceptable.

Increasing parallel for the builder will decrease a host capacity to build a whole push if max_worker_jobs < requested_jobs

Current CPU/MEM utilisation over 1M for hz-bbw8 and 9 is:
- CPU Max around 70 %
- MEM Max around 30 %

This means we can allocate more jobs than CPU's available.
Increased to 110 so that a host will continue to build a whole push.
