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.
