Update dlpack to v1.0rc

[ndgrigorian]

This PR bumps the version of dlpack by bringing in the new dlpack.h from v1.0rc.

As a result of changes introduced in v1.0rc

• get_build_dlpack_version now returns a tuple giving the major and minor DLPack version dpctl was built with
• support for the new DLManagedTensorVersioned struct has been added, including full support of the new flags attribute
• __dlpack__ method of usm_ndarray has been updated to choose between DLManagedTensorVersioned and DLManagedTensor paths based on the new max_version keyword argument, and also now has dl_device and copy keyword arguments
• from_dlpack method has been updated with device and copy keyword arguments and now has a path for arrays supporting the new __dlpack__ interface and DLManagedTensorVersioned. from_dlpack also honors the read-only bitmask that can now be present on a DLManagedTensorVersioned object
• an enumerator class for the DLPack device types has been added to _usmarray.pyx

This pull request also slips in a minor change to usm_ndarray's constructor to honor the writable flag when buffer is another usm_ndarray

@oleksandr-pavlyk The commit from the memory work branch seems to have broken the dlpack tests on Windows.

The check need tweaking:

In [9]: x.__dlpack__(max_version=1)
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
Cell In[9], line 1
----> 1 x.__dlpack__(max_version=1)

File ~/repos/dpctl_tmp/dpctl/tensor/_usmarray.pyx:1131, in dpctl.tensor._usmarray.usm_ndarray.__dlpack__()
   1129 else:
   1130     dpctl_dlpack_version = get_build_dlpack_version()
-> 1131     if max_version >= dpctl_dlpack_version or max_version[0] == dpctl_dlpack_version[0]:
   1132         # DLManagedTensorVersioned path
   1133         # TODO: add logic for targeting a device

TypeError: '>=' not supported between instances of 'int' and 'tuple'

The check should check that max_version is a 2-tuple of integers. But looking at this check, what is the purpose of overriding clause max_version[0] == dpctl_dlpack_version[0]?

Please update dpctl/tensor/include/dlpack/README.md with version and SHA of the vendored dlpack.h

max_version[0] >= dpctl_dlpack_version[0] should be enough.

The spec recommends that if the major versions match, it's a strong enough condition to return a capsule with our own max_version.

It would be good to factor out common code from to_dlpack_capsule and to_dlpack_versioned_capsule into a function.
