Adds IMenu as way to identify menus. Replaces referring to menus as SWindows.
Lots of uses of PushMenu() fixed up to match new API

- Fixed references not being up-to-date as changes are made live in the editor. Simply close and reopen the Size Map to see updated references. (UE-14410)
- Fixed many issues with Size Map not showing the correct set of referenced content by an asset (no longer uses Asset Registry, instead serializes to find references.)
- Fixed 2D textures not reporting correct size (they were reporting current streamed-in mips, not worst-case size)
- Fixed assets that reported zero bytes as their size not being tracked as "unknown size"
- Fixed root-level assets sometimes getting bundled into the "SHARED" group
- Fixed Size Map no longer functioning when viewing large numbers of assets, such as all Engine Content
- Fixed Size Map having to be closed and reopened sometimes to show all of the correct references
- Fixed node text sometimes drawing with unintentionally huge fonts due to integer overflow
- Fixed the asset type name not being shown next to an asset name that had child references
- Fixed hard-to-read text labels due to node colors being desaturated too much at even shallow depth levels
