tools/profile: Add additional information to backtrace (#5109)

Add additional information and change the format of the backtrace:
- Include the symbol base offset and DSO name.
- Symbol and DSO information is included if it's available in the target binary.
- Format:
  [SYMBOL+OFFSET] (MODULE)
- Add a -A(or --addr) option for a detailed format that includes the address:
  ADDR [SYMBOL+OFFSET] (MODULE)
