  [NFC][mlir][ptr] Clarify pointer dialect semantics

This patch adds the following description to the pointer dialect:
```
    The pointer dialect provides types and operations for representing and
    interacting with pointer values in MLIR, such as loading and storing values
    from/to memory addresses.

    The dialect's main type is an opaque pointer (`ptr`) that can be
    parameterized by a memory space. This type represents a handle to an object
    in memory, or target-dependent values like `nullptr`. Further, the dialect
    assumes that the minimum addressable unit by a pointer is a byte. However,
    the dialect does not make assumptions about the size of a byte, which is
    considered a target-specific property.
