Tracing, Logging

Suggestion

In addition to the trace points introduced in #40063, we've had requests for optional tracing of

  • inferTypesFrom
  • invokeOnce
  • getAccessibleSymbolChain
  • typeToTypeNode
  • getIntersectionType
  • getUnionType
  • instantiateType

As a result, we will also require a mechanism for indicating which are active in any given run. (Consider mimicking the format used by the debug package.) However, the default should probably remain similar to what's in #40063 since performance analysis is the primary use case.
