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.

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.

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.

The CL is reverted because it didn't account for the case when a check
of a user-specified type argument against the bound depends on another
type that is only known after type inference is done.

* Ensure that we have a .dill file and it has the correct version before
we start decoding it in dump.dart.
* Throw errors, not strings. Ensure that they have a useful
toString().
* Do not print usage except when the command is invoked
incorrectly (wrong number of arguments). Once we get into the
command it's less likely that it's been invoked incorrectly and more
likely that something else has gone wrong.
Because these utilities are invoked from other scripts (like the
fasta command), printing their usage for problems other than
invoking them correctly doesn't match the way that they were invoked
and it's confusing.

The code in class_hierarchy.dart that looped over override pairs
included implementations inherited from its superclass as potential
overriders, presumably in a broken attempt to include some interface
checks into the mix.
With this problem fixed, the special case in kernel_class_builder.dart
that excluded overriders not declared in the current class (i.e.
declared in a mixin) could be removed without incurring false
positives.
These override checks performed on members from a mixin produce an
extra context message indicating the class where the two members meet,
giving rise to the override relation (similarly to interface checks).
Since the same member can now override more than one member (or even
the same member more than once), the diagnostics message duplication
check has been extended to also include the context in the comparison.
