refactor(compiler): Drop support for the deprecated <template>. Use <ng-template> instead (#22783)

Browse Source 
BREAKING CHANGE:

The `<template>` tag was deprecated in Angular v4 to avoid collisions (i.e. when
using Web Components).

This commit removes support for `<template>`. `<ng-template>` should be used
instead.

BEFORE:

    <!-- html template -->
    <template>some template content</template>

    # tsconfig.json
    {
      # ...
      "angularCompilerOptions": {
        # ...
        # This option is no more supported and will have no effect
        "enableLegacyTemplate": [true|false]
      }
    }

AFTER:

    <!-- html template -->
    <ng-template>some template content</ng-template>

### *enableLegacyTemplate*
The use of `<template>` element was deprecated starting in Angular 4.0 in favor of using
`<ng-template>` to avoid colliding with the DOM's element of the same name. Setting this option to
`true` enables the use of the deprecated `<template>` element . This option
is `false` by default. This option might be required by some third-party Angular libraries.
### *disableExpressionLowering*
The Angular template compiler transforms code that is used, or could be used, in an annotation
