For quite a while it is an unspoken convention to add a trailing
new-line files within the Angular repository. This was never enforced
automatically, but has been frequently raised in pull requests through
manual review. This commit sets up a lint rule so that this is
"officially" enforced and doesn't require manual review.

In environments such as the Language Service where inline type-checking code
is not supported, the compiler would previously produce a diagnostic when a
template would require inlining to check. This happened whenever its
component class had generic parameters with bounds that could not be safely
reproduced in an external TCB. However, this created a bad user experience
for the Language Service, as its features would then not function with such
templates.
Instead, this commit changes the compiler to use the same strategy for
inline TCBs as it does for inline type constructors - falling back to `any`
for generic types when inlining isn't available. This allows the LS to
support such templates with slightly weaker type-checking semantics, which
a test verifies. There is still a case where components that aren't
exported require an inline TCB, and the compiler will still generate a
diagnostic if so.

This commit updates compiler_spec.ts in the Ivy LS suite to utilize the new
testing environment which was introduced in the previous commit. Eventually
all specs should be converted, but converting one right now helps ensure
that the new testing env is working properly and able to support real tests.

The Ivy Language Service codebase testing suite contains a few testing
utilities which allow for assertions of Language Service operations against
an in-memory project. However, this existing utility lacks the flexibility
to test more complex scenarios, such as those involving multiple TS projects
with dependencies between them.
This commit introduces a new 'testing' package for the Ivy LS which attempts
to more faithfully represent the possible states of an IDE, and allows for
testing of more advanced scenarios. The new utility borrows from the prior
version and is geared towards more ergonomic testing. Only basic
functionality is present in this initial implementation, but this will grow
over time.
