Fluent2 DataGrid Style Doesn't Match Theme

### Description

The new Fluent2 DataGrid style is extremely bare-bones and doesn't match the overall theme. This isn't entirely the fault of WPF here or even prior frameworks. DataGrid simply isn't a control in UWP or WinUI3 so it never had an official design done. The community toolkit made an attempt (which is also different than the style here); however, again it doesn't fit in well and clearly isn't done by the Fluent theme designers.


### Reproduction Steps

Just take a look at the current Fluent2 DataGrid style.

### Expected behavior

The WPF team ideally needs to communicate internally with the Microsoft design team and have them fully design this for Fluent. However, the Fluent UI Blazor library already has a version that we could use if this isn't possible:
