fix: High CPU usage in FluentDataGrid

[JamesNK]

🐛 Bug Report

I stress tested Aspire and had a grid with many rows that updated once a second. I noticed very high CPU usage. I profiled and found uncached usage of Expression.Compile().

Likely offender: https://github.com/microsoft/fluentui-blazor/blob/4516f9567354f6d721ac9f78c5ec5e055b7868ef/src/Core/Components/DataGrid/Columns/TemplateColumn.cs#L26-L27

Which is called from RenderRow: https://github.com/microsoft/fluentui-blazor/blob/4516f9567354f6d721ac9f78c5ec5e055b7868ef/src/Core/Components/DataGrid/FluentDataGrid.razor#L89-L106
