params: Decrease -param=max-find-base-term-values= default [PR92264]
For the PR in question, my proposal would be to also lower
-param=max-find-base-term-values=
default from 2000 to 200 after this, at least in the above 4
bootstraps/regtests there is nothing that would ever result in
find_base_term returning non-NULL with more than 200 VALUEs being processed.

PR rtl-optimization/92264
* params.opt (-param=max-find-base-term-values=): Decrease default
from 2000 to 200.
