Summary:
This patch adds onTypeFormatting to clangd.
The trigger character is '}' and it works by scanning for the matching '{' and formatting the range in-between.
There are problems with ';' as a trigger character, the cursor position is before the `|`:
```
int main() {
int i;|
}
```
becomes:
```
int main() { int i;| }
```
which is not likely what the user intended.
Also formatting at semicolon in a non-properly closed scope puts the following tokens in the same unwrapped line, which doesn't reformat nicely.

clangd is a language server protocol implementation based on clang. It's
supposed to provide editor integration while not suffering from the
confined ABI of libclang.
This implementation is limited to the bare minimum functionality of
doing (whole-document) formatting and rangeFormatting. The JSON parsing
is based on LLVM's YAMLParser but yet most of the code of clangd is
currently dealing with JSON serialization and deserialization.
This was only tested with VS Code so far, mileage with other LSP clients
may vary.
