Adds the implementation of the following new instructions:
* `declareLet` - creation-time instruction that initializes the slot for a let declaration.
* `storeLet` - update-time instruction that stores the current value of a let declaration.
* `readContextLet` - instruction that reads the stored value of a let declaration from a different view.
On top of the instructions, it also introduces a new `LetDeclaration` TNode type.
The new TNode is nececessary for DI to work correctly in pipes inside the let expression,
as well as for proper hydration support.

For quite a while it is an unspoken convention to add a trailing
new-line files within the Angular repository. This was never enforced
automatically, but has been frequently raised in pull requests through
manual review. This commit sets up a lint rule so that this is
"officially" enforced and doesn't require manual review.

When looking at `TView` debug template only Element nodes were displayed
as `TNode.Element` was used for both `RElement` and `RText`.
Additionally no text was stored in `TNode.value`. The result was that
the whole template could not be reconstructed. This refactoring creates
`TNodeType.Text` and store the text value in `TNode.value`.
The refactoring also changes `TNodeType` into flag-like structure make
it more efficient to check many different types at once.

is intended to be used by humans while debugging the application with
`ngDevMode` turned on.
In addition this chang also adds jasmine matchers for better asserting
that `LView` is in the correct state.
