Previously, non-bracketed inputs (e.g. `xyz="foo"`) on downgraded components
were initialized using `attrs.$observe()` (which uses `$evalAsync()` under the
hood), while bracketed inputs (e.g. `[xyz]="'foo'"`) were initialized using
`$watch()`. If the downgraded component was created during a `$digest` (e.g. by
an `ng-if` watcher), the non-bracketed inputs were not initialized in time for
the initial call to `ngOnChanges()` and `ngOnInit()`.
This commit fixes it by using `$watch()` to initialize all inputs. `$observe()`
is still used for subsequent updates on non-bracketed inputs, because it is more
performant.
Fixes#16212
- prevents unsubscribing from the zone on error
- prevents unsubscribing from directive `EventEmitter`s on error
- prevents detaching views in dev mode if there on error
- ensures that `ngOnInit` is only called 1x (also in prod mode)

Reworked some of the code so asserts are no longer necessary.
Added additional and potentially redundant checks
Added checks where the null checker found real problems.

Angular uses the `ng-version` attribute to indicate which elements
were used to bootstrap an application. However, after 4.0 we also
added this attribute for all dynamically created components.

When a directive lives on the same element as a component
(e.g. `<my-comp myDir>`), the directive was not able to get hold
of the `ChangeDetectorRef` of the component on that element. However,
as directives are supposed to decorate components, this is incorrect.
This commit enables this use case.
Closes#12816
This commit adds a new parameter to ngc named `missingTranslation` to set the MissingTranslationStrategy for AoT, it takes the value `error`, `warning` or `ignore`.

Previously, when using a different property/attribute name for an upgraded
component's binding (e.g. `bindings: {propName: '<attrName'}`), the property and
attribute names were swapped (e.g. using `attrName` as the property name and
`propName` as the attribute name). This resulted in unexpected behavior.
This commit fixes this using the correct names for properties and attributes.
This only affects `upgrade/dynamic`. `upgrade/static` works correctly already.

This only shows up in the language service. Calls to symbols
that are not resolve resulted in null instead of being resolved
causing the language service to see exceptions when the null
was not expected such as in the animations array.
Fixes#15969
- always have a value for `angular`, even if no angular is on the page
- use `const` instead of `function` to allow to export a variable `module`
without breaking tsickle / closure.
Language service was treating some alias TypeScript symbols as if
they where the canonical symbol. If the symbol in scope is an alias
of another symbol the symbol should be converted to the canonical
symbol.
