test: Update GHA jobs to support new Swift Testing

Split job into macOS and Ubuntu specific jobs
Add concurrency setting to GHA so only one per branch will run at a time
Update GH actions to their latest versions
Replace setup-swift action with xcode-select-version-action and update
    to Xcode 16 on macOS
Build tests when building package
Use --skip testGetPullRequestsPerformance to not run long running tests
Set TEST_GITHUB_TOKEN environment variable at the swift test level
Update test-reporting path to new swift-testing results file path
Add workaround for test-reporting
    issue [1169](actions/checkout#1169)

Switch swift-testing package to use newly released v0.12.0

Update missed Swift Testing migration of XCTSkip to @suite(.disabled())
    in EndpointTests
Change testGetPullRequestsPerformance timeout to 3 minutes

TODO: Collapse macOS and Ubuntu jobs back into one
