feat!: Modify apex-node TestResult to account for test setup data

[CristiCanizales]

What does this PR do?

The new API contract only requires changes to the summary section; addition of a new property, testSetupTimeInMs, and a change in meaning of testTotalTimeInMs. The major change is the new section “setup”, which is less likely to break consumers.

Modify TestResult as follows:

• Add summary property named "testSetupTimeInMs" as a number
• Add a new top level section named "setup" as an array of ApexTestSetupData

For each function that returns TestResult today and is producing test results in the form of TestResultRaw

• Modify it so that it uses a common transform to produce TestResult from TestResultRaw

What issues does this PR fix or reference?

@W-15923420@

Functionality After

• TestResult summary contains new field "testSetupTimeInMs"
• TestResult summary field "testTotalTimeMs" = sum of testSetupTimeInMs and testExecutionTimeMs
• Heap space is not negatively impacted
