codewhisperer: supplemental context strategy id (#560)

Problem:
We need more granular data when processing supplemental context analysis (CrossFile / UTG)
For example, UTG we have 2 different strategies to resolve the source file given a test file (where the customer trigger)
 - by file name
 - by file content

Solution:
Add a strategyId field.
