Introduces `ref-` to give a name to an element or a directive (also works for `<template>` elements), and `let-` to introduce an input variable for a `<template>` element. BREAKING CHANGE: - `#...` now always means `ref-`. - `<template #abc>` now defines a reference to the TemplateRef, instead of an input variable used inside of the template. - `#...` inside of a *ngIf, … directives is deprecated. Use `let …` instead. - `var-...` is deprecated. Replace with `let-...` for `<template>` elements and `ref-` for non `<template>` elements. Closes #7158 Closes #8264
