TreeView: Performance/rendering improvement for big trees with many nodes

[ferberts]

Describe the feature request
What problem does this solve that MatBlazor isn't currently capable of?
TreeView has issues with big datasets. I am currently using it with around 5k entries. I added a checkbox as content and if i check only one box a big amount of components is rendered again slowing down the response time.

Expected behavior
A clear and concise description of what you expected to happen.
I expect that only visual items are rendered, perhaps using virtualize tag or other techniques. Lazy loading works for initial loading, but when items are loaded performance must stay at an acceptable level.

Screenshots
If applicable, add screenshots or .GIF captures to help explain your request.
