When parsing interpolations, if we encounter an empty interpolation
(`{{}}`), the current code uses a "pretend" value of `$implicit` for the
name as if the interplotion were really `{{$implicit}}`. This is
problematic because the spans are then incorrect downstream since they
are based off of the `$implicit` text.
This commit changes the interpretation of empty interpolations so that
the text is simply an empty string.

This commit adds special handling to the completion builder by detecting
a two way binding context and ensuring that we filter out any `Input`s
that do not support two way binding.
PR Close#40185
This comit adds support for autocompletion of attributes that create
structural directives. Such completions differ from those of normal
attributes, as the structural directive syntax creates a synthetic
<ng-template> node which has different attributes from the main element.
PR Close#40032
This commit adds attribute completion to the Language Service. It completes
from 3 sources:
1. inputs/outputs of directives currently present on the element
2. inputs/outputs/attributes of directives in scope for the element, that
would become present if the input/output/attribute was added
3. DOM properties and attributes
We distinguish between completion of a property binding (`[foo|]`) and a
completion in an attribute context (`foo|`). For the latter, bindings to
the attribute are offered, as well as a property binding which adds the
square bracket notation.
To determine hypothetical matches (directives which would become present if
a binding is added), directives in scope are scanned and matched against a
hypothetical version of the element which has the attribute.

This commit expands the autocompletion capabilities of the language service
to include element tag names. It presents both DOM elements from the Angular
DOM schema as well as any components (or directives with element selectors)
that are in scope within the template as options for completion.

This commit extends the template targeting system, which determines the node
being referenced given a template position, to return additional context if
needed about the particular aspect of the node to which the position refers.
For example, a position pointing to an element node may be pointing either
to its tag name or to somewhere in the node body. This is the difference
between `<div|>` and `<div foo | bar>`.

This commit adds support to the Language Service for autocompletion within
expression contexts. Specifically, this is auto completion of property reads
and method calls, both in normal and safe-navigational forms.
PR Close#39727
This commit adds support in the Ivy Language Service for autocompletion in a
global context - e.g. a {{foo|}} completion.
Support is added both for the primary function `getCompletionsAtPosition` as
well as the detail functions `getCompletionEntryDetails` and
`getCompletionEntrySymbol`. These latter operations are not used yet as an
upstream change to the extension is required to advertise and support this
capability.
