ref: Create thread inspector Swift protocol

[noahsmartin]

This removes SentryThreadInspector from the dependency container public interface, in favor of a protocol defined in Swift. This means we don't need to convert the entire thing to Swift before the dependency container

Resolves https://linear.app/getsentry/issue/COCOA-608/convert-sentrycrashstackentrymapper-to-swift and https://linear.app/getsentry/issue/COCOA-708/convert-sentrythreadinspector and https://linear.app/getsentry/issue/COCOA-707/convert-sentrystacktracebuilder

Note

Replaces public SentryThreadInspector exposure with Swift protocols and a SentryDefaultThreadInspector implementation, updating dependencies, integrations, and tests accordingly.

• Thread Inspection:
  • Add Swift protocols SentryThreadInspector and SentryThreadInspecting for thread inspection.
  • Rename Obj-C class SentryThreadInspector → SentryDefaultThreadInspector and migrate call sites.
• Core/DI:
  • SentryDependencyContainer: expose threadInspector as id<SentryThreadInspector> and lazily instantiate SentryDefaultThreadInspector.
  • SentryClient: ctor now takes/creates SentryDefaultThreadInspector and stores it; uses it for attaching threads/stacktraces.
• Integrations:
  • Update ANR, Core Data, File I/O, Network tracking to depend on protocol or SentryDefaultThreadInspector and use getCurrentThreads*/stacktraceForCurrentThreadAsyncUnsafe.
• Swift/Obj-C bridges & Tests:
  • Add new Swift files: SentryThreadInspector.swift, SentryThreadInspecting.swift.
  • Rename tests to SentryDefaultThreadInspectorTests; adapt helpers (TestThreadInspector) and bridging headers/imports.
• Misc:
  • SentryProfileTimeseries.h: switch UIKit import to SentryProfilerDefines.

I'm a bit confused. Can't the SentryThreadInspector implement the SentryThreadInspecting protocol? Then, the SentryDependencyContainer doesn't need to have a private property @property (nonatomic, strong) SentryThreadInspector *threadInspector;. We can have one public property for the new interface SentryThreadInspecting and it whould work.

Thanks @philipphofmann just made those changes
