Max Desiatov 7ec0837778 Embedded WASI: fix concurrency-deleted-method.swift test ...

The test was crashing due to `swift_unreachable("custom executors not supported in embedded Swift")` line in `swift_task_enqueueImpl`, as the corresponding non-embedded codepath was relying on an unspecialized generic function `_swift_task_enqueueOnExecutor` defined in `Executor.swift`. Unspecialized generics are unavailable in Embedded Swift, and such `@silgen_name` function can't be specialized when used from concurrency runtime code written in C/C++. We can redefine this function for Embedded Swift as using a class-bound existential instead, and re-enable this codepath with a slightly different call that avoids the use of unavailable `swift_getObjectType` function from the non-embedded runtime.
