A bunch of changes to pave the way for emebdder SDK summary creation.
* Moves _embedder.yaml processing into the embedder SDK (out of the resolver).
* Changes EmbedderUriResolver to compose rather than extend a DartUriResolver.
* Fixes the wierd handling (dropping to add back) of `dart:` URIs.
* Fixes the incorrect overriding docs for `SDKLibraryImpl.shortName`.
* Updates embedder test to include a definition of `dart:core` in anticipation of adding some embedder SDK tests.
Some API work TODO in a follow-up CL (notably the way we check for the presence of embedders by querying the resolver is odd).

Addresses the issue seen in https://github.com/dart-lang/sdk/issues/26448.
Ultimately we want a better story for summaries in the presence of embedded SDKs; in the short-term this simply disables them.
The trick (and reason for all of the changes here) is that there is *a lot* of temporal coupling in the initiailization of contexts, sdks, resolvers, etc. With this change, embedder processing is pulled out to where it can be done before the SDK is configured. Hopefully this even makes this a bit more clear as resolver setup is less complex.
Open question: I think the logic that calls `pub list-dirs` is dead and can safely be removed. Comments there welcome.
Thanks!

Fixes: https://github.com/dart-lang/sdk/issues/26129
The issue was that we were creating the SDK and populating its options (notably `strong-mode`) *before* options processors were called. The result was that client code analysis contexts and SDK contexts were getting configured differently causing confusion when client code was getting analyzed with a non-strong-mode SDK.

This simplifies the integration with build systems such as Bazel, in
which it is sometimes convenient to have a build unit which depends on
other build units but doesn't introduce any additional source files of
its own.

The hashes were being thrown away anyway; computing them just wastes
time.
Cuts the runtime of generating an AST-based summary of the analyzer
package (with a warm VM) by about 19%.

When building summaries from ASTs, we only use the context to read
source files; we don't need it to provide an element model. Therefore,
we can save some time by turning off the context's use of summaries,
because this prevents it from trying to eagerly deserialize the
summaries of dart:async and dart:core.
Saves a significant amount of time when building a summary of a small
package using ASTs. For example, saves ~37% of time when building a
strong mode summary of the "yaml" package.

When summaries are built in fallback mode, the only information stored
in the package bundle is (a) which libraries appear in the bundle, and
(b) where the source files can be found on disk. This is enough
information so that DDC will still be able to tell how libraries are
grouped into build units, but otherwise summary functionality is
disabled.
This is intended to be availadle as a temporary workaround so that if
a bug is found in the summary infrastructure, it won't prevent DDC
compilation from working (it will just make it slower).

It (in combination with --build-summary-only-diet) makes the
package:path summary is almost 3 times smaller, partially because of
skipping bodies, patially because of excluding documentation comments,
and partially because of making 'codeRange' fields informative.
We also remove MD5 hashes.
As I can see after changes in method bodies we generate the exactly
same file (or at least 'cmp -l' thinks so). Adding a new field results
in a file of different length.

Build mode differs from package mode in the following ways:
- The analyzer no longer guesses the relationship between paths and
URIs based on directory structure. Instead, each input file is
specified in the form "$uri|$path".
- The analyzer does not read any files from disk that are not
specified on the command line.
- There are no restrictions on the relationship between summaries and
packages. In particular: (a) multiple input summaries may summarize
parts of the same package, and (b) part of a package may be
specified with an input summary while an output summary is being
generated for other parts of the same package.
- Output may be redirected to a file.
- The analyzer may be told to exit with success even in the event that
an error is found during analysis.
This should ease the integration with Bazel, and provide a starting
point for integrating with other build systems.

This is similar to --package-warnings, except that diagnostics will
only be reported for Dart packages matching the given prefix.
Also added the number of source files analyzed and the number of
errors generated to performance report.
Cleanup: simplified code for triggering diet parsing.
