fix: use caseCount for parameterized test progress in both event parsers

recordTestCaseResult in xcodebuild-event-parser hardcoded += 1 for all
count increments, ignoring the caseCount field from parameterized Swift
Testing results. Also made the XCTest fallback path in the Swift Testing
event parser consistent.
