trace: make call depth limit customizable
Up to now we had hard coded values for the call depth up to which trace
records are created: 200 for early tracing, 15 thereafter. UEFI
applications reach a call depth of 80 or above.
Provide customizing settings for the call trace depth limit and the early
call trace depth limit. Use the old values as defaults.
