[fidl][dart] Final fixes to make Dart compat green

(This incorporates changes which were started in
I51ec696e3a3e6fb4a954c9c7d1d39e7eae982452.)

We change the `Encoder` to take whether it should operate in
unions-as-xunions mode explicitely. The codegen is modified to use
the default value, and pass that explicitely.

The header is properly writtent with the flag set when writing
unions-as-xunions.

The bindings are changed to read the header bits,
indicating whether to use the unions-as-xunions on decode path.

Methods now have their old and v1 request/response sizes, which is then
used appropriately in the generated bindings code to allocate, position,
and claim buffer reads/writes.

Note: we change the compatibility test in the stacked CL since it also
relies on depedent CLs in fuchsia.git which have not yet globally
integrated.

Topaz

Topaz augments system functionality by implementing interfaces defined by underlying layers. Topaz contains four major categories of software: modules, agents, shells, and runners.

For example, modules include the dashboard, and runners include the Web, Dart, and Flutter runners.
