LOG: [mlir][mesh] Refactoring code organization, tests and docs (#79606)
* Split out `MeshDialect.h` form `MeshOps.h` that defines the dialect
class. Reduces include clutter if you care only about the dialect and
not the ops.
* Expose functions `getMesh` and `collectiveProcessGroupSize`. There
functions are useful for outside users of the dialect.
* Remove unused code.
* Remove examples and tests of mesh.shard attribute in tensor encoding.
Per the decision that Spmdization would be performed on sharding
annotations and there will be no tensors with sharding specified in the
type.
For more info see this RFC comment:

For Example on a 3D mesh an operation with `mesh_axes = [0, 2]` would specify
an in-group device with `(i, j)`. Then for each group with index `g` on the
second axis, the in-group device would be `(i, g, j)`.

Collectives that involve the whole device group to perform a single operation
are pure. The exceptions are `send` and `recv`.
