[roll] Roll fuchsia [ktrace_provider] Support kKernelStreamingSupport if Enabled
Sets up ktrace_provider to use the kernel streaming support if enabled.
This means it can now call zx_ktrace_read repeatedly during the trace,
so we now do so on a fixed frequency.
Be sure to enable streaming mode to use it:
Usage:
Add `command_line_args = ["ktrace.bufsize=1"]` into your developer
overrides.
```
assembly_developer_overrides(...) {
...
kernel {
command_line_args = ["ktrace.bufsize=1"]
}
...
}
```
Then run the ffx command:
```
ffx trace start --duration 120 --categories #default --buffering-mode streaming
```
