feat: support cancellation/timeouts on condition evaluation

[jpadilla]

Description

• Use ContextEval instead of Eval https://pkg.go.dev/github.com/google/cel-go/cel#Program.ContextEval
• Set a default of 100 for InterruptCheckFrequency https://pkg.go.dev/github.com/google/cel-go/cel#InterruptCheckFrequency

In aa117f1, I added two temporary benchmark suites to get an idea of how long evaluations might take based on the expression + parameters supplied. Notice the p99(ns) column.
