[clang-format] Fix putting ObjC message arguments in one line for multiline receiver
Summary:
Reapply reverted changes from D46879.
Currently BreakBeforeParameter is set to true everytime message receiver spans multiple lines, e.g.:
```
[[object block:^{
return 42;
}] aa:42 bb:42];
```
will be formatted:
```
[[object block:^{
return 42;
}] aa:42
bb:42];
```
even though arguments could fit into one line. This change fixes this behavior.
Test Plan:
make -j12 FormatTests && tools/clang/unittests/Format/FormatTests
