The partial compiler will add a version number to the objects that are
generated so that the linker can select the appropriate partial linker
class to process the metadata.
Previously this version matching was a simple number check. Now
the partial compilation writes the current Angular compiler version
into the generated metadata, and semantic version ranges are used
to select the appropriate partial linker.

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.

For consistency with other generated code, the partial declaration
functions are renamed to use the `ɵɵ` prefix which indicates that it is
generated API.
This commit also removes the declaration from the public API golden
file, as it's not yet considered stable at this point. Once the linker
is finalized will these declaration function be included into the golden
file.

This commit adds the basic building blocks for linking partial declarations.
In particular it provides a generic `FileLinker` class that delegates to
a set of (not yet implemented) `PartialLinker` classes.
The Babel plugin makes use of this `FileLinker` providing concrete classes
for `AstHost` and `AstFactory` that work with Babel AST. It can be created
with the following code:
```ts
const plugin = createEs2015LinkerPlugin({ /* options */ });
```
