`getCurrentDirectory` directory doesn't return a posix separated normalized path. While `rootDir` and `rootDirs` should return posix separated paths, it's best to not assume as other paths within the compiler options can be returned not posix separated such as `basePath`
See: https://github.com/Microsoft/TypeScript/blob/master/src/compiler/sys.ts#L635
This partially fixes#29140, however there needs to be a change in the CLI as well to handle this, as at the moment we are leaking devkit paths which is not correct.

Sometimes declarations are not exported publicly but are exported under
a private name. In this case, rather than adding a completely new
export to the entry point, we should create an export that aliases the
private name back to the original public name.
This is important when the typings files have been rolled-up using a tool
such as the [API Extractor](https://api-extractor.com/). In this case
the internal type of an aliased private export will be removed completely
from the typings file, so there is no "original" type to re-export.
For example:
If there are the following TS files:
**entry-point.ts**
```ts
export {Internal as External} from './internal';
```
**internal.ts**
```ts
export class Internal {
foo(): void;
}
```
Then the API Extractor might roll up the .d.ts files into:
```ts
export declare class External {
foo(): void;
}
```
In this case ngcc should add an export so the file looks like:
```ts
export declare class External {
foo(): void;
}
export {External as Internal};
```

ngsummary files were generated with an export for each class declaration.
However, some Angular code declares classes (class Foo) and exports them
(export {Foo}) separately, which was causing incomplete summary files.
This commit expands the set of symbol names for which summary exports will
be generated, fixing this issue.

Previously, when the NgModule scope resolver discovered semantic errors
within a users NgModules, it would throw assertion errors. TODOs in the
codebase indicated these should become ts.Diagnostics eventually.
Besides producing better-looking errors, there is another reason to make
this change asap: these assertions were shadowing actual errors, via an
interesting mechanism:
1) a component would produce a ts.Diagnostic during its analyze() step
2) as a result, it wouldn't register component metadata with the scope
resolver
3) the NgModule for the component references it in exports, which was
detected as an invalid export (no metadata registering it as a
component).
4) the resulting assertion error would crash the compiler, hiding the
real cause of the problem (an invalid component).
This commit should mitigate this problem by converting scoping errors to
proper ts.Diagnostics. Additionally, we should consider registering some
marker indicating a class is a directive/component/pipe without actually
requiring full metadata to be produced for it, which would allow suppression
of errors like "invalid export" for such invalid types.

`ng_module` will now include an `src/r3_symbol.d.ts` when compiling the core package under `ngc` togather with `dts bundling`, This is due that `ngcc` relies on this file to be present, but the `r3_symbols` file which is not part of our public api.

This commit refactors and expands ngtsc's support for generating imports of
values from imports of types (this is used for example when importing a
class referenced in a type annotation in a constructor).
Previously, this logic handled "import {Foo} from" and "import * as foo
from" style imports, but failed on imports of default values ("import
Foo from"). This commit moves the type-to-value logic to a separate file and
expands it to cover the default import case. Doing this also required
augmenting the ImportManager to track default as well as non-default import
generation. The APIs were made a little cleaner at the same time.

In the TypeScript compiler API, emit() can be performed either on a single
ts.SourceFile or on the entire ts.Program simultaneously.
ngtsc previously used whole-program emit, which was convenient to use while
spinning up the project but has a significant drawback: it causes a type
checking operation to occur for the whole program, including .d.ts files.
In large Bazel environments (such as Google's codebase), an ngtsc invocation
can have a few .ts files and thousands of .d.ts inputs. This unwanted type
checking is therefore a significant drain on performance.
This commit switches ngtsc to emit each .ts file individually, avoiding the
unwanted type checking.

When processing a JavaScript program, TS may come across a symbol that has
been imported from a TypeScript typings file.
In this case the compiler may pass the ReflectionHost a `prototype` symbol
as an export of the class.
This pseudo-member symbol has no declarations, which previously caused the
code in `Esm5ReflectionHost.reflectMembers()` to crash.
Now we just quietly ignore such a symbol and leave `Esm2015ReflectionHost`
to deal with it.
(As it happens `Esm2015ReflectionHost` also quietly ignores this symbol).

Prior to this commit, i18n instructions (i18n, i18nStart) were generated before listener instructions. As a result, event listeners were attached to the wrong element (text node, not the parent element). This change updates the order of instructions and puts i18n ones after listeners, to make sure listeners are attached to the right elements.

For the template type checking to work correctly, it needs to know
what attributes are bound to expressions or directives, which may
require expressions in the template to be evaluated in a different
scope.
In inline templates, there are attributes that are now marked as
"Template" attributes. We need to ensure that the template
type checking code looks at these "bound" attributes as well as the
"input" attributes.
PR Close#29041
The content projection mechanism is static, in that it only looks at the static
template nodes before directives are matched and change detection is run.
When you have a selector-based content projection the selection is based
on nodes that are available in the template.
For example:
```
<ng-content selector="[some-attr]"></ng-content>
```
would match
```
<div some-attr="..."></div>
```
If you have an inline-template in your projected nodes. For example:
```
<div *ngIf="..." some-attr="..."></div>
```
This gets pre-parsed and converted to a canonical form.
For example:
```
<ng-template [ngIf]="...">
<div some-attr=".."></div>
</ng-template>
```
Note that only structural attributes (e.g. `*ngIf`) stay with the `<ng-template>`
node. The other attributes move to the contained element inside the template.
When this happens in ivy, the ng-template content is removed
from the component template function and is compiled into its own
template function. But this means that the information about the
attributes that were on the content are lost and the projection
selection mechanism is unable to match the original
`<div *ngIf="..." some-attr>`.
This commit adds support for this in ivy. Attributes are separated into three
groups (Bindings, Templates and "other"). For inline-templates the Bindings
and "other" types are hoisted back from the contained node to the `template()`
instruction, so that they can be used in content projection matching.

This commit adds a new `AttributeMarker` type that will be used, in a

Prior to this change, the RegExp that was used to check for dashes in field names used "g" (global) flag that retains lastIndex, which might result in skipping some fields that should be wrapped in quotes (since lastIndex advanced beyond the next "-" location).

This update gives external tooling the ability for async providers to

ngtsc occasionally converts a type reference (such as the type of a
parameter in a constructor) to a value reference (argument to a
directiveInject call). TypeScript has a bad habit of sometimes removing
the import statement associated with this type reference, because it's a
type only import when it initially looks at the file.
A solution to this is to always add an import to refer to a type position
value that's imported, and not rely on the existing import.

With 6215799055 we introduced schematics

We don't want to run these schematic tests in the legacy-saucelabs job,
as these are node-only specs and the non-Bazel Karma setup is not set
up to provide the devkit schematic node modules.
