[lldb] Load the fblldb module automatically 

Summary:
```
// Facebook only:
// We want to load automatically the fblldb python module as soon as lldb or
// lldb-vscode start. This will ensure that logging and formatters are enabled
// by default.
//
// As we want to have a mechanism for not triggering this by default, if the
// user is starting lldb disabling .lldbinit support, then we also don't load
// this module. This is equivalent to appending this line to all .lldbinit
// files.
//
// We don't have the fblldb module on windows, so we don't include it for that
// build.
```

Test Plan:
the fbsymbols module is loaded automatically

```
./bin/lldb
(lldb) help fbsymbols
Facebook {mini,core}dump utility.  Expects 'raw' input (see 'help raw-input'.)
```
