This patch initializes the `ptr` dialect directories and base files, adding the `!ptr.ptr` type and the `#ptr.spec<...>` data layout spec attribute. The `!ptr.ptr` type is an opaque pointer type optionally parameterized by a memory space. This type typically represents a handle to an object in memory or target-dependent values like `nullptr`. The implementation of the `DataLayoutTypeInterface` interface for `!ptr.ptr` was adapted from `!llvm.ptr`'s implementation. This implementation uses the `#ptr.spec<...>` attribute for defining the data layout specification. See [[RFC] `ptr` dialect & modularizing ptr ops in the LLVM dialect](https://discourse.llvm.org/t/rfc-ptr-dialect-modularizing-ptr-ops-in-the-llvm-dialect/75142) for rationale and roadmap.
