Summary:
Previously, `clang-format` didn't understand lightweight
Objective-C generics, which have the form:
```
@interface Foo <KeyType,
ValueTypeWithConstraint : Foo,
AnotherValueTypeWithGenericConstraint: Bar<Baz>, ... > ...
```
The lightweight generic specifier list appears before the base
class, if present, but because it starts with < like the protocol
specifier list, `UnwrappedLineParser` was getting confused and
failed to parse interfaces with both generics and protocol lists:
```
@interface Foo <KeyType> : NSObject <NSCopying>
```
Since the parsed line would be incomplete, the format result
would be very confused (e.g., https://bugs.llvm.org/show_bug.cgi?id=24381).
This fixes the issue by explicitly parsing the ObjC lightweight
generic conformance list, so the line is fully parsed.

Test Plan: New tests added. Ran tests with:
% make -j16 FormatTests && ./tools/clang/unittests/Format/FormatTests
