This is a major revamp of bytecode metadata format. Now bytecode has
its own serialization mechanisms.
This CL adds 'bytecode component' metadata, which contains bytecode
object table and string table. All references from bytecode (constant
pools) to libraries, classes, members, types and strings now have a new
format. References to frequently used objects are represented as indices
in object table, while rarely used objects are written inline.
This allows VM to cache frequently used objects while reading bytecode.
Representation of strings is aligned with VM - string characters are
stored in separate pools of one-byte and two-byte strings. This allows
VM to avoid UTF-8 decoding and extra copying.
Closure declarations are now explicit. Type parameters no longer require
enslosing scopes when reading/writing them.

Also includes changes to the kernel and front_end pubspecs, since
those packages are tightly coupled to the analyzer.
These changes were made on the analyzer-0.33 branch in preparation for
previous releases of the analyzer. Merging them to the master branch
makes it easier to keep the pubspec and CHANGELOG files up to date on
that branch.

Previously we had several places where different uriToSource was used.
This was both weird and led to errors when something refering to
some state was used to look up in another state.
This CL makes it so we only have one source of truth.
To not include sdk sources when serializing a component that only mixes
something from the sdk in, (or extends it or...), the serialization is
changed slightly to keep track of which uris come from actual
implementation. Before the sdk sources was explicitly removed in the
incremental compiler, but we want to limit those kinds of things,
which is why we're doing it differently here.
Fixes#35215.

For all other "debugPath.add"s we've wrapped it in assert to avoid
doing it in the general case.
One apparently have slipped through.

This is a breaking change, so the analyzer major version number is
bumped. However, we don't need to publish a new analyzer yet so we
use a "-dev" version number.
This breaking change requires upgrading to the latest version of the
linter package.

Previously, we only stored a reference to the originating Typedef declaration
and is thus loosing the originating type arguments. We need these type arguments
in various places, including diagnostics and bounds checks.
Note: this CL maintains backwards compatibility wrt to the Dart API of
FunctionType. I'll update the API in a follow-up CL.
