build: enable strictTemplates, strictBindCallApply, and strictFunctionTypes

[Splaktar]

• enable Ivy's strict Template Type Checking
• fix related build errors
• complete this._destroyed in ngOnDestroy()
• exclude dist/ from linting

strictPropertyInitialization is a bit more problematic, so it will be handled in a separate PR.

I'm also not really concerned w/ turning on strictPropertyInitialization, which doesn't play super well w/ Angular in general

LGTM

I think the previous approach was valid, you just needed to do themeName! since it's guaranteed to be defined.

    this._queryParamSubscription = this._activatedRoute.queryParamMap
    .pipe(map((params: ParamMap) => params.get('theme')), filter(Boolean))
    .subscribe((themeName: string) => this.installTheme(themeName!));

Results in:

ERROR in src/app/shared/theme-picker/theme-picker.ts:74:16 - error TS2769: No overload matches this call.

                  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  node_modules/rxjs/internal/types.d.ts:64:5

This compiles, but is not great...

.subscribe((themeName: any) => this.installTheme(themeName));
