Reland of https://dart-review.googlesource.com/c/sdk/+/29160
Adds a 'severity' field to diagnostic messages and replaces all
addWarning and addNit functions by a generic addProblem, which uses
the intrinsic severity of the message. Eventually, errors should
also be reported this way.
A special severity value maps into either warning or error for Dart 1
and Dart 2, respectively. Most Dart 1 warnings are in this category.
Fixes some 320 failures of DDK test expecting a compile-time error.
These were previously masked by a workaround in the DDC error handler
which has now been removed.

Before: Kernel static errors were represented by throwing a distinguished
error or else by calling a distinguished library const constructor.
Now: Kernel static errors are represented by InvalidExpression. To support
error reporting, InvalidExpression has an optional message and a file
offset. A back end can choose to signal these errors at any time; for
example, when deserializing the binary, or when compiling the procedure
containing the static error, or when the erroneous expression is evaluated
at run time.
InvalidStatement is removed because it can be encoded as ExpressionStatement
of InvalidExpression.
Future work:
* supporting static errors where an expression cannot appear in the AST
* allowing InvalidExpression to contain an Expression for error recovery
* adding a top-level list of static errors and warnings to the binary

This includes two fixes that only caused problems in windows:
- we assumed file-uris in other parts of DDK, and this caused problems with sourcemaps
- we generated module names containing a leading "./" (e.g. "./expect"), this didn't cause trouble in linux, but it is incorrect.

This involves a few main pieces:
- Add code to the GN scripts to generate DDC's patched SDK and then
compile it to summaries and JS in the build output directory.
- Add support to the underlying DDC build scripts to support controlling
which files are built where.
- Update test.dart to use the DDC SDK from the build directory.
- Update create_sdk to use the built SDK instead of the checked in one.
- Fix various internal DDC tools to build their own copy of the SDK
(since they can't easily find the one in the build directory because
it's path if config-specific) and use those.
- Delete the checked DDC SDK JS and summaries.
I think I got everything working. The built Dart SDK looks fine -- it's
identical to one built using the old build scripts.
The various tools and DDC's little test runner I *think* work, but there
may be a bug or two in there. I tried the various things I could and it
seems like they work but it's hard to tell since they may be kind of
broken right now anyway.
