Previously, `RefCountedPtr<>` and `WeakRefCountedPtr<>` incorrectly allowed
implicit casting of any type to any other type. This hadn't caused a
problem until recently, but now that it has, we need to fix it. I have
fixed this by changing these smart pointer types to allow type
conversions only when the type used is convertible to the type of the
smart pointer. This means that if `Subclass` inherits from `Base`, then
we can set a `RefCountedPtr<BaseClass>` to a value of type
`RefCountedPtr<Subclass>`, but we cannot do the reverse.
We had been (ab)using this bug to make it more convenient to deal with
down-casting in subclasses of ref-counted types. For example, because
`Resolver` inherits from `InternallyRefCounted<Resolver>`, calling
`Ref()` on a subclass of `Resolver` will return `RefCountedPtr<Resolver>`
rather than returning the subclass's type. The ability to implicitly
convert to the subclass type made this a bit easier to deal with. Now
that that ability is gone, we need a different way of dealing with that
problem.
I considered several ways of dealing with this, but none of them are
quite as ergonomic as I would ideally like. For now, I've settled on
requiring callers to explicitly down-cast as needed, although I have
provided some utility functions to make this slightly easier:
- `RefCounted<>`, `InternallyRefCounted<>`, and `DualRefCounted<>` all
provide a templated `RefAsSubclass<>()` method that will return a new
ref as a subclass. The type used with `RefAsSubclass()` must be a
subclass of the type passed to `RefCounted<>`, `InternallyRefCounted<>`,
or `DualRefCounted<>`.
- In addition, `DualRefCounted<>` provides a templated `WeakRefAsSubclass<T>()`
method. This is the same as `RefAsSubclass()`, except that it returns
a weak ref instead of a strong ref.
- In `RefCountedPtr<>`, I have added a new `Ref()` method that takes
debug tracing parameters. This can be used instead of calling `Ref()`
on the underlying object in cases where the caller already has a
`RefCountedPtr<>` and is calling `Ref()` only to specify the debug
tracing parameters. Using this method on `RefCountedPtr<>` is more
ergonomic, because the smart pointer is already using the right
subclass, so no down-casting is needed.
- In `WeakRefCountedPtr<>`, I have added a new `WeakRef()` method that
takes debug tracing parameters. This is the same as the new `Ref()`
method on `RefCountedPtr<>`.
- In both `RefCountedPtr<>` and `WeakRefCountedPtr<>`, I have added a
templated `TakeAsSubclass<>()` method that takes the ref out of the
smart pointer and returns a new smart pointer of the down-casted type.
Just as with the `RefAsSubclass()` method above, the type used with
`TakeAsSubclass()` must be a subclass of the type passed to
`RefCountedPtr<>` or `WeakRefCountedPtr<>`.
Note that I have *not* provided an `AsSubclass<>()` variant of the
`RefIfNonZero()` methods. Those methods are used relatively rarely, so
it's not as important for them to be quite so ergonomic. Callers of
these methods that need to down-cast can use
`RefIfNonZero().TakeAsSubclass<>()`.

This fixes#21619. This experimental ALPN protocol has already been removed from the other gRPC stacks.

Also, in the trace statements, capture the file/line that the sequence was constructed at, and log that with the traces.

upb currently defines upb_Message to be void but that may soon change, at which point the gRPC build would break without these casts.
This time for sure! With C++-style casts that also actually build!

`AllOk` runs a set of promises concurrently, and like `TryJoin` waits for them all to succeed or one to fail.
Unlike `TryJoin` it returns a single unified status of the composition, so cannot handle member promises that might return `StatusOr` or the like.

The upb gencode is being changed to no longer generate _has_() functions for repeated fields as they are redundant and really only intended for scalar fields with presence. So instead of calling foo_has_bar(msg), one now calls foo_bar(msg, &size) to get the number of elements in the repeated field.

### Changes in this PR
* Refactor and remove some Core/C++ dependencies to simplify Python Observability package build process.
* Refactored code to read config at Python layer.
* Enable observability build from source.
* Add observability to run_test.
* Currently it's only enabled in Linux.
* Add error handler in run_test loaders.
* Current framework will always visit modules in test directory then decide which tests to skip.
* Since we're not building Observability for MacOS and Windows this step will fail with error `No module named 'grpc_observability'`.
* After the change we'll just skip those modules.
* We still have `_sanity_test` to make sure all tests are loaded correctly for each platform.
* Remov OC dependency as we're migrating to OTel.
* Also removed trace from testing.
* Note that trace propagation function was also removed because of this.
### Testing
* Passed existing tests.
* Tested locally, able to build observability from source using `GRPC_PYTHON_BUILD_WITH_CYTHON=1 pip install .`.
