With the introduction of the partial compilation, the Angular compiler's
existing `parseTemplate` method has been extended to pass through multiple
properties purely in favor of the partial compilation.
e.g. the `parseTemplate` function now accepts an "option" called `isInline`.
This option is just passed through and returned as part of the `ParsedTemplate`.
This is not ideal because the `parseTemplate` function doesn't care
whether the specified template was inline or not. This commit cleans
up the `parseTemplate` compiler function so that nothing needed only
for the partial compilation is added to it.
We introduce a new struct for additional template information that
is specific to the generation of the `declareComponent` function. With
that change, we can simplify the component decorator handler and keep
logic more local.

This commit changes the partial compilation so that it outputs declarations
rather than definitions for injectables.
The JIT compiler and the linker are updated to be able to handle these
new declarations.

The partial declaration of a component includes the list of directives
that are used in its template, including some metadata of the directive
which can be used during actual compilation of the component. Used
components are currently part of this list, as components are also
directives. This commit splits the used components into a dedicate
property in the partial declaration, which allows for template
compilation to optimize the generated code for components.

There were a number of almost identical interfaces used in
the same way throughout the Render3 compiler code.
This commit changes the compiler to use the same interface
throughout.

The `template` and `isInline` fields were previously stored in a nested
object, which was initially done to accommodate for additional template
information to support accurate source maps for external templates. In
the meantime the source mapping has been accomplished in a different
way, and I feel this flattened structure is simpler and smaller so is
preferable over the nested object. This change also makes the `isInline`
property optional with a default value of `false`.

When partially compiling a component with an external template, we must
synthesize a new AST node for the string literal that holds the contents of
the external template, since we want to source-map this expression directly
back to the original external template file.

The `ɵɵngDeclareComponent` calls are designed to be translated to fully
AOT compiled code during a build transform, but in cases this is not
done it is still possible to compile the declaration object in the
browser using the JIT compiler. This commit adds a runtime
implementation of `ɵɵngDeclareComponent` which invokes the JIT compiler
using the declaration object, such that a compiled component definition
is made available to the Ivy runtime.

The types of directives and pipes that are used in a component's
template may be emitted into the partial declaration wrapped inside a
closure, which is needed when the type is declared later in the module.
This poses a problem for JIT compilation of partial declarations, as
this closure is indistinguishable from a class reference itself. To mark
the forward reference function as such, this commit changes the partial
declaration codegen to emit a `forwardRef` invocation wrapped around
the closure, which ensures that the closure is properly tagged as a
forward reference. This allows the forward reference to be treated as
such during JIT compilation.

This allows the code generation to correspond with a type, which is
helpful for documentation and discoverability purposes. This does not
offer any type-safety with respect to the actually generated code.

This commit implements partial compilation of components, together with
linking the partial declaration into its full AOT output.
This commit does not yet enable accurate source maps into external
templates. This requires additional work to account for escape sequences
which is non-trivial. Inline templates that were represented using a
string or template literal are transplated into the partial declaration
output, so their source maps should be accurate. Note, however, that
the accuracy of source maps is not currently verified in tests; this is
also left as future work.
The golden files of partial compilation output have been updated to
reflect the generated code for components. Please note that the current
output should not yet be considered stable.
