Before this commit, attribute completion display parts were retrieved
but not assigned. In addition, the switch case was non-exhaustive
because it did not include `StructuralDirectiveAttribute`.

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.

Both `ReferenceSymbol` and `VariableSymbol` have two locations of
interest to an external consumer.
1. The location for the initializers of the local TCB variables allow consumers
to query the TypeScript Language Service for information about the initialized type of the variable.
2. The location of the local variable itself (i.e. `_t1`) allows
consumers to query the TypeScript LS for references to that variable
from within the template.

This commit refactors the QuickInfo abstraction shared between the VE and
Ivy services and used to implement hover tooltips (quick info), which was
extracted from the VE code in commit faa81dc. The new DisplayParts
abstraction is more general and can be used to extract information needed by
various LS functions (e.g. autocompletion).
This commit effectively reverts faa81dc, returning the original code to the
VE implementation as the Ivy code is now diverged.
