trace_processor: add Id wrapper type returned by Insert in all db tables

uint32_t was being used to represent both ids and row indices. This is
not a problem for root tables (as the id always equals the index) but
for child tables, this is not the case and can lead to bad out of
bounds errors.

Reduce the confusion by introducing a new Id type for each table
heirarchy. The Id is defined is the root table and is used as the return
type of Insert in all child tables. This ensures that there can be no
conversion between row indices and ids without explicitly converting
between the two.
