9671d6b37c [swift-inspect] Fix corpse leaks when target doesn't have libswiftCore loaded. 
In DarwinRemoteProcess's early return when libswiftCore.dylib isn't loaded in the process, we hadn't initialized all stored properties yet, which means our deinit didn't run. This leaked the task. This is especially bad when forking a corpse, as the system has a very limited number of corpses available.

Add a Cleanup helper to manage resources that need explicit cleanup. This is a noncopyable struct which takes a cleanup function and calls it whenever a new value is set or when the struct is destroyed. Use this for the DarwinRemoteProcess properties that need explicit cleanup. This allows us to remove DarwinRemoteProcess's deinit and always run these cleanups regardless of how we exit the initializer.

While we're here, fix the truncations of buffer in getAllProcesses.

0b953adb44 SwiftInspectLinux: re-order initialization 
It seems that a recent change to the compiler will now optimize the
initializer and then the SIL verifier will fail due to the unintialized
member when the initializer is throwing and will never return without
initializing the member unless the initialization fails.

115b2b7bcb [swift-inspect] Use decimal format for Task ID (#80309) 
Use decimal to display Task IDs. This matches changes being done else where to use decimal consistently for Task IDs. For example https://github.com/swiftlang/swift/pull/80154 and https://github.com/swiftlang/llvm-project/pull/10308.

b3a430d175 [swift-inspect] On Darwin, don't try to inspect processes that don't have Swift. 
When we locate libswiftCore.dylib in the remote process, check for failure and give up immediately if we don't find one. If the process doesn't have Swift, there's no point in trying to inspect anything in it.
