The function property of a Code object can contain either a Function or
a NativeFunction. This change updates the protocol specification to
properly document existing behavior and regenerates package:vm_service
to update `CodeRef.function` to have a `dynamic` type.
This is a breaking change to `package:vm_service`, so this will be
released as 15.0.0.

service/get_object_rpc_test was failing because one ID in it hadn't been
updated to the new format.
service/bad_reload_test was failing because `ServiceEvent::PrintJSON`
was attempting to populate the `reloadError` property of every `Event`
of kind `IsolateReload` with an `@Error`, but it was not possible to
allocate IDs for these `@Error`s because `ReloadSources` runs for an
isolate group, not for an individual isolate. I fixed this by removing
the `reloadError` property and adding a `reloadFailureReason` property
with type `string`.

Currently we decode incoming data as a string, then parse the string as
JSON.
We can do it in one step by fusing a `Utf8Decoder` with a `JsonDecoder`,
which will be faster.
A difference between `jsonDecode` and the fused version is that
`jsonDecode` returns `dynamic`, the fused version returns `Object?`.
To keep changes as small as possible we cast the return value of the
fused verison to `dynamic` in this CL.
However using `dynamic` values is often slower than type casting it to
the right type and then using it. So it might make sense to cast it to
something like `Map<String, dynamic>` in a separate CL.

This adds fast paths that avoid copying bytes from the input to a
temporary array when the current chunk has enough bytes for thing being
parsed.
Also avoids allocating a temporary array when parsing a 64-bit float by
allocating a single 8-byte buffer and reusing it.
This reduces runtime of a `HeapSnapshotGraph.fromChunks` call parsing a
91M snapshot in a single chunk from 2 seconds to 1.8 seconds. The
benchmark code is compiled with `dart2js -O4`.

Previously, when taking a tear-off, a separate Context object was
allocated in order to capture receiver. Now, receiver is stored directly
in the Closure object in the 'context' field. This saves 1 object
allocation per tear-off and makes tear-offs cheaper compared to
explicit closures which can share context with other closures.

To reduce the headache associated with adding parameters to VM service
APIs, VmServiceInterface has been removed from package:vm_service and
pulled into its own dedicated package:vm_service_interface. This will
help reduce the need for major version bumps of package:vm_service,
which requires manual version bumps through >8 packages in order to make
the latest version available to flutter_tools and DevTools.
This separation of the VmService client from the interface will reduce
the frequency of major version bumps to `package:vm_service` as adding
optional parameters to existing APIs would cause implementers of the
interface to break.
package:vm_service continues to expose a copy of the contents of package:vm_service_interface to avoid breaking google3 rolls until package:dwds can migrate to package:vm_service_interface. package:vm_service will not be published until this copy is removed.
This change also includes:
- some code cleanup and modernization to both the code generator and
generated code
- >=3.0.0 SDK version requirement to allow for new language features

This CL also adds:
1. a method `vmServiceConnectUriWithCreator` helper alongside the existing `vmServiceConnectUri` helper. This method can create a generic `VmService` instance with the same logic as the existing `vmServiceConnectUri` helper. This was implemented this way so that it is not a breaking change to the existing helper.
2. a typedef `VmServiceCreator` for use in the `vmServiceConnectUriWithCreator` method and for shared use in packages that depend on `package:vm_service` (e.g. the DevTools packages)
3. a static method `VmService.defaultCreator` that provides a `VmServiceCreator` method for the `VmService` class.
