[Swift Testing] Add Swift-callable wrapper around InstanceMethodSwizzler for
TestWebKitAPI
https://bugs.webkit.org/show_bug.cgi?id=312797
rdar://175186623
Reviewed by Richard Robinson.
Swift tests in TestWebKitAPI have no ergonomic way to mock Objective-C
runtime behavior: the C++ InstanceMethodSwizzler RAII helper is awkward
to use from Swift, which prefers scoped `with*` functions over dropping
an RAII handle on the floor. This is the first piece of infrastructure
needed to port AppKit-heavy tests (NSPasteboard mocks, NSMenu pop-ups,
gesture recognizers, drag-and-drop) to the new Swift Testing framework.
Add ObjectiveCMethodSwizzling.swift, exposing two scoped helpers:
- `withSwizzledObjectiveCInstanceMethod(replacing:name:with:perform:)`
swaps in a block-derived IMP for an instance method.
- `withSwizzledObjectiveCClassMethod(replacing:name:with:perform:)`
is the class-method counterpart, backed by `class_getClassMethod`.
Both take an `@convention(block)` closure whose first parameter is the
receiver (or receiving class) followed by the method's arguments, and
both restore the original implementation via `defer` before returning,
including on error paths. They also call `imp_removeBlock` to balance
`imp_implementationWithBlock`.
