[lldb] More tests for DumpDataExtractor

* Using a base address or skipping it with LLDB_INVALID_ADDRESS
* Using a data offset, which does not effect the printed addresses
* Not providing an output stream
* Formatting a double sized HexFloat
* Formatting over multiple lines

Since address printing now has its own test,
I've removed the base address from all the format
type tests.

The multi line tests still use a base address to check that
it's incremented correctly for each new line.
