perf db-export: Add trace begin / end branch type variants
Add branch types to cover different combinations with "trace begin" or
"trace end".
Previously, the Intel PT decoder would indicate begin / end by a branch
from / to zero. That hides useful information, in particular when a
trace ends with a call. Before remedying that, prepare the database
export to export branch types with more combinations that include trace
begin / end. In those cases extend the descriptions to include 'trace
begin' and 'trace end' separately.
