Working towards turning on all lints from package:pedantic. This change includes
the lints that needed cleanup and don't change any behavior.
Applied cleanup:
* Don't explicitly initialize variables to null.
* DO use curly braces for all flow control structures.
* Use `.isEmpty` instead of `.length == 0`.
* Use `.isNotEmpty` instead of `.length > 0` or `! .isEmpty`.
* Use `=` to separate a named parameter from its default value.
The remaining lints from package:pedantic will require cleanup that is less
automatic and will be addressed in later changes.

The new file pkg/dev_compiler/lib/src/analyzer/driver.dart handles
building the linked summary for a build unit, and then is capable of
doing analysis using LibraryAnalyzer.
The algorithm is very similar to analyzer_cli's build mode. The
biggest difference is that `dartdevc` has existing support for
discovering source files from the explicit source list (rather than
requiring every source to be listed on the command line). We don't want
to break that support, so there's a bit of logic to follow imports,
exports, and parts.
After the linked summary is produced, DDC gets the analysis results
(errors and resolved AST) for each library, and compiles it into a JS
module.

This adds a method to the internal SDK runtime library that can be
called to clear state when a hot restart is desired.
This also refactors some of the logic around ignoring type errors,
as we need to ensure we can clear those caches. Also I noticed a bug
where the result of isSubtypeOf was assumed to be non-null, but this
was not the case. The new structure should make this more clear.
(Note: I think we may be able to remove a lot of the code for ignoring
type errors soon.)

Most of the fixes are around things like special optimized annotations
used in our SDK code, that were not understood by DDK. Also some inline
JS type annoations were not correct.

This change improves DDC/DDK source maps:
- fix Analyzer backend step locations to pass all of the tests
Kernel was passing. Also improves breakpoints and code coverage.
- fix Analyzer backend to mark hover spans where possible, such as
fields, parameters, locals, `this`, properties, methods, etc.
- refactor DDC/DDK backends to emit source locations, rather than
pointers to Analyzer/Kernel tree nodes.
- unify/simplify source_map_printer between Analyzer/Kernel backends.
- source_map_printer understands JS expression nesting, marking the
innermost JS expression offset corresponding to a given Dart offset.
This preserves hover tooltips, even for expressions with implicit
coercions (e.g. `dart.test(x)`)
- source_map_printer understands that JS end-of-function markings need
to be before the closing brace.
- merge _visitAndMarkExpression and _visitExpression to simplify
Analyzer & Kernel backends.
- fix test expectations where the column location was too specific.
- adds a message to the stepping test runner to help future debugging.
- removes optional destructuring support from Analyzer backend. This
was unused/untested and added complexity. Instead we should decide
if/when to fully switch to destructuring, and then do so.
