Add CBO parameter for configuring Shuffle Elimination cutoff

Adds configurable Shuffle Elimination cutoff option based on number of joins in a query. This option is primarily needed for benchmarking CBO with Shuffle Elimination on different queries, PR with benchmarks is going to be to merged at github <#27065>, but since it also changes yql/essentials, this PR on Arcanum needs to be merged first.
