Before the `ngDevMode` had to be set explicitly or it would throw
an exception at runtime. This changes it so that if `ngDevModu` is
`undefined` than we default to `ngDevMode = true`. In other words
unless the developer has explicitly asked to make a prodution build
by setting `ngDevMode = false` as compilation constant, the default
is `ngDevMode = true`.
This also fixes a minor bug where the setup code would read
`global['ngDevMode']` but all other code would read `global.ngDevMode`.
This would cause issues with closure compiler since the
reading of the `ngDevMode` must be consistent.

Update XMB placeholders(<ph>) to include the original value on top of an
example. Placeholders can by definition have one example(<ex>) tag and a
text node. The text node is used by TC as the "original" value from the
placeholder, while the example should represent a dummy value.
For example: <ph name="PET"><ex>Gopher</ex>{{ petName }}</ph>.
This change makes sure that we have the original text, but it *DOES NOT*
make sure that the example is correct. The example has the same wrong
behavior of showing the interpolation text rather than a useful
example.
No breaking changes, but tools that depend on the previous behavior and
don't consider the full XMB definition may fail to parse the XMB.

In some code formats (e.g. ES5) methods can actually be function
expressions. For example:
```js
function MyClass() {}
// this static method is declared as a function expression
MyClass.staticMethod = function() { ... };
```

The `ReflectionHost` interface that is being implemented only expects a
return value of `boolean`.
Moreover, if you want to extend this class to support non-TS code formats,
e.g. ES5, the result of this call returning true does not mean that the `node`
is a `ClassDeclaration`. It could be a `VariableDeclaration`.

- `directiveInjector()` is used to inject anything in the directive / component
/ pipe factories so adding `InjectionToken<T>` as a supported token type.
- `getOrCreateInjectable()` should search first in the node injector tree and
then in the module injector tree (was either or before the PR).

This commit replaces the "not implemented" error when calling
listLazyRoutes() with an empty result, which will allow testing
in the CLI before listLazyRoutes() is implemented.

loadNgStructureAsync() for ngtsc has a bug where it returns a
Promise<Promise[]> instead of awaiting the entire array of Promises.
This commit uses Promise.all() to await the whole set.

compile_strategy() is used to decide whether to build Angular code
using ngc (legacy) or ngtsc (local). In order for g3 BUILD rules
to switch properly and allow testing of Ivy in g3, they need to
import this function.
This commit removes the _ prefix which allows the function to be
imported.

ngtsc used to have a custom ts.CompilerHost which delegated to the plain
ts.CompilerHost. There's no need for this wrapper class and it causes
issues with CLI integration, so delete it.

ngtsc used to assume that all .d.ts dependencies (that is, third party
packages) were imported via an absolute module path. It turns out this
assumption isn't valid; some build tools allow relative imports of
other compilation units.
In the absolute case, ngtsc assumes (and still does) that all referenced
types are available through the entrypoint from which an @NgModule was
imported. This commit adds support for relative imports, in which case
ngtsc will use relative path resolution to determine the imports.

There is a bug in the existing handling for cross-file references.
Suppose there are two files, module.ts and component.ts.
component.ts declares two components, one of which uses the other.
In the Ivy model, this means the component will get a directives:
reference to the other in its defineComponent call.
That reference is generated by looking at the declared components
of the module (in module.ts). However, the way ngtsc tracks this
reference, it ends up comparing the identifier of the component
in module.ts with the component.ts file, detecting they're not in
the same file, and generating a relative import.
This commit changes ngtsc to track all identifiers of a reference,
including the one by which it is declared. This allows toExpression()
to correctly decide that a local reference is okay in component.ts.
PR Close#25080
When ngtsc encounters a reference to a type (for example, a Component
type listed in an NgModule declarations array), it traces the import
of that type and attempts to determine the best way to refer to it.
In the event the type is defined in the same file where a reference
is being generated, the identifier of the type is used. If the type
was imported, ngtsc has a choice. It can use the identifier from the
original import, or it can write a new import to the module where the
type came from.
ngtsc has a bug currently when it elects to rely on the user's import.
When writing a .d.ts file, the user's import may have been elided as
the type was not referred to from the type side of the program. Thus,
in .d.ts files ngtsc must always assume the import may not exist, and
generate a new one.
In .js output the import is guaranteed to still exist, so it's
preferable for ngtsc to continue using the existing import if one is
available.
This commit changes how @angular/compiler writes type definitions, and
allows it to use a different expression to write a type definition than
is used to write the value. This allows ngtsc to specify that types in
type definitions should always be imported. A corresponding change to
the staticallyResolve() Reference system allows the choice of which
type of import to use when generating an Expression from a Reference.

@ContentChild[ren] and @ViewChild[ren] can contain a forwardRef() to a
type. This commit allows ngtsc to unwrap the forward reference and
deal with the node inside.
It includes two modes of support for forward reference resolution -
a foreign function resolver which understands deeply nested forward
references in expressions that are being statically evaluated, and
an unwrapForwardRef() function which deals only with top-level nodes.
Both will be useful in the future, but for now only unwrapForwardRef()
is used.
