gh-128902: Fix check for fallthrough attribute support (#128903) 
Clang versions prior to 10 (which corresponds to Apple Clang 12) do not
support the GCC extension syntax __attribute__((fallthrough)), but do
evaluate __has_attribute(fallthrough) to 1 because they support the
C++11 style syntax [[fallthrough]]. The only way to tell if the GCC
style syntax is supported is thus to check the clang version.

GH-128520: Make pathlib._abc.WritablePath a sibling of ReadablePath (#129014) 
In the private pathlib ABCs, support write-only virtual filesystems by
making `WritablePath` inherit directly from `JoinablePath`, rather than
subclassing `ReadablePath`.

There are two complications:

- `ReadablePath.open()` applies to both reading and writing
- `ReadablePath.copy` is secretly an object that supports the *read* side
  of copying, whereas `WritablePath.copy` is a different kind of object
  supporting the *write* side

We untangle these as follow:

- A new `pathlib._abc.magic_open()` function replaces the `open()` method,
  which is dropped from the ABCs but remains in `pathlib.Path`. The
  function works like `io.open()`, but additionally accepts objects with
  `__open_rb__()` or `__open_wb__()` methods as appropriate for the mode.
  These new dunders are made abstract methods of `ReadablePath` and
  `WritablePath` respectively.  If the pathlib ABCs are made public, we
  could consider blessing an "openable" protocol and supporting it in
  `io.open()`, removing the need for `pathlib._abc.magic_open()`.
- `ReadablePath.copy` becomes a true method, whereas `WritablePath.copy` is
  deleted. A new `ReadablePath._copy_reader` property provides a
  `CopyReader` object, and similarly `WritablePath._copy_writer` is a
  `CopyWriter` object. Once GH-125413 is resolved, we'll be able to move
  the `CopyReader` functionality into `ReadablePath.info` and eliminate
  `ReadablePath._copy_reader`.

gh-111178: fix UBSan failures in Modules/_ctypes (#129071) 
This fixes UBSan failures for the following objects:

- `DictRemoverObject` and `StructParamObject`,
- `CDataObject` and `CFieldObject`, and
- `PyCFuncPtrObject` and `PyCArgObject`.

On the default build, we convert the `LOCK_PTR` and `UNLOCK_PTR` macros to
functions with an unused parameter to ease "unused variable" compiler warnings
suppression. Finally, we also remove some redundant casts to `PyObject *`.
