tracing/remotes: Fix TRACE_REMOTE build when TRACING=n

Browse Source 
TRACE_REMOTE relies on tracefs, eventfs and ring-buffer which are only
built and declared when TRACING is enabled. It is however possible for a
config to have FTRACE=y TRACING=n and TRACE_REMOTE=y.

To fix this configuration, have TRACE_REMOTE select TRACING directly,
just like other FTRACE options do and drop the TRACING dependency from
NVHE_EL2_TRACING to avoid a circular Kconfig dependency.
