[ktrace_provider] Remove use of kernel.Reader

ktrace_provider uses a fidl call to the long deprecated Platform Bus
driver from DFv1. This provided a small abstraction over calling
zx_ktrace_control directly.

With a more modern approach, we directly route the debug resource to
ktrace_provider and just call the system call directly. This removes a
bunch of copying through the fidl channel, and set up for removing the
tracing portion of the platform bus entirely.
