[SourceKit] Add request to expand macros syntactically

Browse Source 
Expand macros in the specified source file syntactically (without any
module imports, nor typechecking).

Request would look like:
```
{
  key.compilerargs: [...]
  key.sourcefile: <file name>
  key.sourcetext: <source text> (optional)
  key.expansions: [<expansion specifier>...]
}
```
`key.compilerargs` are used for getting plugins search paths. If
`key.sourcetext` is not specified, it's loaded from the file system.
Each `<expansion sepecifier>` is
```
{
  key.offset: <offset>
  key.modulename: <plugin module name>
  key.typename: <macro typename>
  key.macro_roles: [<macro role UID>...]
}
```
Clients have to provide the module and type names because that's
semantic.

Response is a `CategorizedEdits` just like (semantic) "ExpandMacro"
refactoring. But without `key.buffer_name`. Nested expnasions are not
supported at this point.
