This commit adds a devMode-only check which will throw if a user
attempts to bind a property that does not match a directive
input or a known HTML property.
Example:
```
<div [unknownProp]="someValue"></div>
```
The above will throw because "unknownProp" is not a known
property of HTMLDivElement.
This check is similar to the check executed in View Engine during
template parsing, but occurs at runtime instead of compile-time.
Note: This change uncovered an existing bug with host binding
inheritance, so some Material tests had to be turned off. They
will be fixed in an upcoming PR.

When we first started writing tests for Ivy, we did not yet have a
compatible compiler. For this reason, we set up the Ivy runtime tests
to run with generated code that we wrote by hand (instead of real code
generated by the compiler).
Now that we have a working Ivy compiler and TestBed infrastructure
that is compatible with Ivy, we should start writing integration
tests that leverage them (no more handwritten generated code!). This
will prevent bugs where the compiler code and runtime code become
out of sync (which is easy if they are tested separately). And
eventually, we should migrate all the existing runtime tests in
"core/test/render3" to TestBed and ngtsc.
To kick off this effort, this commit migrates some existing tests
from "core/test/render3/exports_spec.ts" and saves them in a new file
with the same name in the "core/test/acceptance" folder.

i18n instructions create text nodes dynamically and save them between bindings and the expando block in `LView`. e.g., they try to create the following order in `LView`.
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando (dirs, injectors) -- |
```
Each time a new text node is created, it is pushed to the end of the array and the `expandoStartIndex` marker is incremented, so the section begins slightly later. This happens in `allocExpando`.
This is fine if no directives have been created yet. The end of the array will be in the "dynamic text node" section.
| -- elements -- | -- bindings -- | -- dynamic i18n text -- |
However, this approach doesn't work if dynamic text nodes are created after directives are matched (for example when the directive uses host bindings). In that case, there are already directives and injectors saved in the "expando" section. So pushing to the end of `LView` actually pushes after the expando section. What we get is this:
```
| -- elements -- | -- bindings -- | -- dynamic i18n text -- | -- expando -- | -- dynamic i18n text-- |
```
In this case, the `expandoStartIndex` shouldn't be incremented because we are not inserting anything before the expando section (it's now after the expando section). But because it is incremented in the code right now, it's now pointing to an index in the middle of the expando section.
This PR fixes that so that we only increment the `expandoStartIndex` if nothing was pushed into the expando section.

Ivy allows Components to extend Directives (but not the other way around) and as a result we may have Component and Directive annotations present at the same time. The logic that resolves annotations to pick the necessary one didn't take this into account and as a result Components were recognized as Directives (and vice versa) in case of inheritance. This change updates the resolution logic by picking known annotation that is the nearest one (in inheritance tree) and compares it with expected type. That should help avoid mis-classification of Components/Directives during resolution.

Previously, attempting to destroy a view with listeners more than once
throws an error during event listener cleanup. This happens because
`cleanup` field on the `TView` has already been cleared out by the time
the second destruction runs.
The `destroyed` flag on LView was previously being set in the `destroyLView` function,
but this flag was never _checked_ anywhere in the codebase. This commit
moves _setting_ this flag to the `cleanupView` function, just before
destroy hooks are called. This is necessary because the destroy hooks
can contain arbitrary user code, such as (surprise!) attempting to
destroy the view (again). We also add a check to `destroyLView` to skip
already-destroyed views. This prevents the cleanup code path from running twice.

By its nature, Ivy alters the import graph of a TS program, adding imports
where template dependencies exist. For example, if ComponentA uses PipeB
in its template, Ivy will insert an import of PipeB into the file in which
ComponentA is declared.
Any insertion of an import into a program has the potential to introduce a
cycle into the import graph. If for some reason the file in which PipeB is
declared imports the file in which ComponentA is declared (maybe it makes
use of a service or utility function that happens to be in the same file as
ComponentA) then this could create an import cycle. This turns out to
happen quite regularly in larger Angular codebases.
TypeScript and the Ivy runtime have no issues with such cycles. However,
other tools are not so accepting. In particular the Closure Compiler is
very anti-cycle.
To mitigate this problem, it's necessary to detect when the insertion of
an import would create a cycle. ngtsc can then use a different strategy,
known as "remote scoping", instead of directly writing a reference from
one component to another. Under remote scoping, a function
'setComponentScope' is called after the declaration of the component's
module, which does not require the addition of new imports.

ngcc's reflection host needs to be able to determine all members of a
class, which it does by using the `ts.Symbol` from TypeScript's
TypeChecker. Such Symbol however may represent multiple class members
in the case of accessors; an equally named getter/setter accessor pair
is combined into a single `ts.Symbol`.
This commit introduces logic to recognize such accessors in order for
both the getter and setter to be considered as class member, similar to
ngtsc's behavior when operating on original TypeScript code.
One difference wrt the TypeScript host is that ngcc cannot see to which
accessor originally had any decorators applied to them, as decorators
are applied to the property descriptor in general, not a specific accessor.
If an accessor has both a setter and getter, any decorators are only
attached to the setter member.

Prior to this change, accessor functions for getters and setters would
