Add functionality to export settings
For the reproducer feature I need to be able to export and import the
current LLDB configuration. To realize this I've extended the existing
functionality to print settings. With the help of a new formatting
option, we can now write the settings and their values to a file
structured as regular commands.
Concretely the functionality works as follows:
(lldb) settings export -f /path/to/file
This file contains a bunch of settings set commands, followed by the
setting's name and value.
...
settings set use-external-editor false
settings set use-color true
settings set auto-one-line-summaries true
settings set auto-indent true
...
You can import the settings again by either sourcing the file or using
the settings read command.
(lldb) settings read -f /path/to/file
