Remove I prefix from TS types

[etimberg]

Standardizes all of the typescript types to drop the I prefix. For example IEvent is now just Event.

The only non-standard change is IInteractionMode which changed to InteractionModeMap because InteractionMode was already defined.

[!] TypeError: Cannot destructure property column of 'undefined' or 'null'.

Something collides?

Perhaps, but the TSC lint works. On the command line I see circular errors, but I think those are pre-existing.

types/core/index.d.ts -> types/platform/index.d.ts -> types/core/index.d.ts
types/core/index.d.ts -> types/platform/index.d.ts -> types/core/interfaces.d.ts -> types/core/index.d.ts
types/controllers/index.d.ts -> types/core/index.d.ts -> types/platform/index.d.ts -> types/core/interfaces.d.ts -> types/interfaces.d.ts -> types/controllers/index.d.ts
...and 9 more

I got the build working locally. I think we'll need to investigate the linter, some of these should have been caught by that. There were two bad imports (IFontSpec and IChartArea) that VSCode rename symbol had missed. No idea why the linter didn't catch that. There was also a conflict definition of FillTarget and DateAdapter became recursive.
