Perf: Optimize FE performance of inline edit with rich text editor

[Koc]

We have a large table with many multi line text fields. The problem is that currently RichEditor component created too early (even before we start editing field). And this early creation adds an tons of event listeners to handle click outside. And sometimes it sends too many updates to BE (even if field wasn't changed).

My PR delays creation of the RichEditor component: now we creating it only for inline editing, not earlier.

Related to #2212 and #2174
