Follow-up from [this discussion](https://github.com/angular/angular/pull/33419#discussion_r339296216). In Ivy we don't use the schema to validate tag names, but instead we use feature detection to figure out whether an element is supported. While this should generally be more accurate, it'll also end up throwing for some more innocent cases. E.g. now Ivy throws an error for `main` elements in IE which is accurate since IE doesn't support the element, but is annoying since there is no functionality attached.
These changes switch to logging a warning instead, similarly to what we're doing for unknown properties.

The `getProjectAsAttrValue` in `node_selector_matcher` finds the
ProjectAs marker and then additionally checks that the marker appears in
an even index of the node attributes because "attribute names are stored
at even indexes". This is true for "regular" attribute bindings but
classes, styles, bindings, templates, and i18n do not necessarily follow
this rule because there can be an uneven number of them, causing the
next "special" attribute "name" to appear at an odd index. To address
this issue, ensure ngProjectAs is placed right after "regular"
attributes.

Prior to this commit, there were no `advance` instructions generated before `i18nExp` instructions and as a result, lifecycle hooks for components used inside i18n blocks were flushed too late.

The main logic of the `InheritDefinitionFeature` is to go through the prototype chain of a given Component and merge all Angular-specific information onto that Component def. The problem happens in case there is a Component in a hierarchy that also contains the `InheritDefinitionFeature` (i.e. it extends some other Component), so it inherits all Angular-specific information from its super class. As a result, the root Component may end up having duplicate information inherited from different Components in hierarchy.
Let's consider the following structure: `GrandChild` extends `Child` that extends `Base` and the `Base` class has a `HostListener`. In this scenario `GrandChild` and `Child` will have `InheritDefinitionFeature` included into the `features` list. The processing will happend in the following order:
- `Child` inherits `HostListener` from the `Base` class
- `GrandChild` inherits `HostListener` from the `Child` class
- since `Child` has a parent, `GrandChild` also inherits from the `Base` class
The result is that the `GrandChild` def has duplicated host listener, which is not correct.
This commit introduces additional logic that checks whether we came across a def that has `InheritDefinitionFeature` feature (which means that this def already inherited information from its super classes). If that's the case, we skip further fields-related inheritance logic, but keep going though the prototype chain to look for super classes that contain other features (like NgOnChanges), that we need to invoke for a given Component def.

Fixes an error that is thrown when a provider is overridden in `TestBed`, if the module definition of one of the imported modules uses a function for the `imports` that is set via `setNgModuleScope`. The problem was that we have a `for...of` loop that assumes that the imports are an array, but they can also be a function. This was handled correctly in other places, but this one was missed.
Note that the above-mentioned error is only thrown at runtime when the code is transpiled to es6. In es5 TS generates a call to a helper that handles the error silently so the attached unit test only fails in es6.

Currently we only run Saucelabs on PRs using the legacy View Engine
build. Switching that build to Ivy is not trivial and there are various
options:
1. Updating the R3 switches to use POST_R3 by default. At first glance,
this doesn't look easy because the current ngtsc switch logic seems to
be unidirectional (only PRE_R3 to POST_R3).
2. Updating the legacy setup to run with Ivy. This sounds like the easiest
solution at first.. but it turns out to be way more complicated. Packages
would need to be built with ngtsc using legacy tools (i.e. first building
the compiler-cli; and then building packages) and View Engine only tests
would need to be determined and filtered out. Basically it will result in
re-auditing all test targets. This is contradictory to the fact that we have
this information in Bazel already.
3. Creating a new job that runs tests on Saucelabs with Bazel. We specify
fine-grained test targets that should run. This would be a good start
(e.g. acceptance tests) and also would mean that we do not continue maintaining
the legacy setup..
This commit implements the third option as it allows us to move forward
with the general Bazel migration. We don't want to spend too much time
on our legacy setup since it will be removed anyway in the future.

The `ModuleWithProviders` type has an optional type parameter that
should be specified to indicate what NgModule class will be provided.
This enables the Ivy compiler to statically determine the NgModule type
from the declaration files. This type parameter will become required in
the future, however to aid in the migration the compiler will detect
code patterns where using `ModuleWithProviders` as return type is
appropriate, in which case it transforms the emitted .d.ts files to
include the generic type argument.
This should reduce the number of occurrences where `ModuleWithProviders`
is referenced without its generic type argument.

Occasionally a factory function needs to be generated for an "invalid"

This commit changes the JIT compiler to generate a new `invalidFactoryDep`

This commit fixes a compatibility bug where pre-order lifecycle
hooks (onInit, doCheck, OnChanges) for directives on the same
host node were executed based on the order the directives were
matched, rather than the order the directives were instantiated
(i.e. injection order).
This discrepancy can cause issues with forms, where it is common
to inject NgControl and try to extract its control property in
ngOnInit. As the NgControl directive is injected, it should be
instantiated before the control value accessor directive (and
thus its hooks should run first). This ensures that the NgControl
ngOnInit can set up the form control before the ngOnInit
for the control value accessor tries to access it.

Originally, QueryList implemented Iterable and provided a Symbol.iterator
on its prototype. This caused issues with tree-shaking, so QueryList was
refactored and the Symbol.iterator added in its constructor instead. As
part of this change, QueryList no longer implemented Iterable directly.
Unfortunately, this meant that QueryList was no longer assignable to
Iterable or, consequently, NgIterable. NgIterable is used for NgFor's input,
so this meant that QueryList was not usable (in a type sense) for NgFor
iteration. View Engine's template type checking would not catch this, but
Ivy's did.
As a fix, this commit adds the declaration (but not the implementation) of
the Symbol.iterator function back to QueryList. This has no runtime effect,
so it doesn't affect tree-shaking of QueryList, but it ensures that
QueryList is assignable to NgIterable and thus usable with NgFor.

Currently if a consumer does something like the following, the object literal will be shared across the two elements and any instances of the component template. The same applies to array literals:
```

These changes make it so that we generate a pure function even if an object is constant so that each instance gets its own object.
Note that the original design for this fix included moving the pure function factories into the `consts` array. In the process of doing so I realized that pure function are also used inside of directive host bindings which means that we don't have access to the `consts`.
These changes also:
* Fix an issue that meant that the `pureFunction0` instruction could only be run during creation mode.
* Make the `getConstant` utility slightly more convenient to use. This isn't strictly required for these changes to work, but I had made it as a part of a larger refactor that I ended up reverting.

The `ngInjectableDef` property was renamed to `ɵprov`, but core must
still support both because there are published libraries that use the
older term.

the defintion is specifically for the given type.
Previously if you tried to inject a class that had `ngInjectableDef` but

Most of the use of `document` in the framework is within
the DI so they just inject the `DOCUMENT` token and are done.
Ivy is special because it does not rely upon the DI and must
get hold of the document some other way. There are a limited
number of places relevant to ivy that currently consume a global
document object.
The solution is modelled on the `LOCALE_ID` approach, which has
`getLocaleId()` and `setLocaleId()` top-level functions for ivy (see
`core/src/render3/i18n.ts`). In the rest of Angular (i.e. using DI) the
`LOCALE_ID` token has a provider that also calls setLocaleId() to
ensure that ivy has the same value.
This commit defines `getDocument()` and `setDocument() `top-level
functions for ivy. Wherever ivy needs the global `document`, it calls
`getDocument()` instead. Each of the platforms (e.g. Browser, Server,
WebWorker) have providers for `DOCUMENT`. In each of those providers
they also call `setDocument()` accordingly.
