[VectorDistribute] Refactor layout configuration to a simpler logic (#21883)

This patch refactors the layout configuration for mma intrinsics to a
much simpler implementation and documents it better. This implementation
will eventually allow us to stop using subgroup_m_count/subgroup_n_count
attributes and use subgroup_basis to control setting number of subgroups
on each dimension.

This patch is mostly NFC, except it removes the ability to greedily
distribute multiple subgroups to multiple dimensions automatically. This
path was not used or maintained. We will eventually have the ability to
do it in following patches once we switch to subgroup_basis.

The test deleted checks the greedy distribution to multiple subgroups
ability which was not used anywhere else.

The tuning spec is changed because it was actually wrong and the
compiler was falsely accepting the configuration. The new configuration
will crash on this invalid specification.
