Previously, the compileComponent() and compileDirective() APIs still required
the output of global analysis, even though they only read local information
from that output.
With this refactor, compileComponent() and compileDirective() now define
their inputs explicitly, with the new interfaces R3ComponentMetadata and
R3DirectiveMetadata. compileComponentGlobal() and compileDirectiveGlobal()
are introduced and convert from global analysis output into the new metadata
format.
This refactor also splits out the view compiler into separate files as
r3_view_compiler_local.ts was getting unwieldy.
Finally, this refactor also splits out generation of DI factory functions
into a separate r3_factory utility as the logic is utilized between different
compilers.

g3 and the Angular repo have different versions of TypeScript, and
ts.updateIdentifier() has a different signature in the different versions.
There is no way to write a call to the function that will compile in both
versions simultaneously.
Instead, use ts.getMutableClone() as that has the same effect of cloning
the identifier.

This commit adds a new compiler pipeline that isn't dependent on global
analysis, referred to as 'ngtsc'. This new compiler is accessed by
running ngc with "enableIvy" set to "ngtsc". It reuses the same initialization
logic but creates a new implementation of Program which does not perform the
global-level analysis that AngularCompilerProgram does. It will be the
foundation for the production Ivy compiler.
