Monaco perf improvement: Optimize editor.layout calls

[vivek1729]

The layout method instructs the editor to remeasure itself and resize if the container has changed since the last update. Under the hood, the layout method tries to call some core DOM apis to get the size of the container DOM element iff there are no params passed to this method.

nteract/packages/monaco-editor/src/MonacoEditor.tsx

Lines 387 to 388 in d2088d0

	// Tells the editor pane to check if its container has changed size and fill appropriately
	this.editor.layout();

It might be worth exploring if this call is needed here and if we can optimize it by passing some expected height/width.
