生成 Dart 版的 Foundation

先用 Foundation 试水，遇到的问题列在这个 Issue 里，逐个解决:

生成代码功能问题：
- [x] 枚举优化: NS_ERROR_ENUM, NS_CLOSED_ENUM
- [ ] 区分泛型和协议，语法很相似，包含参数、返回值中的。（'id' 和 NSArray<ObjectType> 分别转成 XXXProtocol 和 List）
- [ ] 生成函数指针声明(FunctionPointer), 处理含有函数指针的内容，如
```
@property (readonly, copy) NSArray<void (^)(void)> *executionBlocks;
@property (nullable) NSUInteger (*hashFunction)(const void *item, NSUInteger (* _Nullable size)(const void *item));
```
- [ ] 重构 typedef（现在写死成解析 Block，应区分其他情况，比如定义函数指针）
- [x] 解析 @property (readonly) const void *bytes NS_RETURNS_INNER_POINTER; 时误把 bytes 当做类型，原因跟 typeSpecifier 出现多次有关。
- [x] 生成 API_DEPRECATED_WITH_REPLACEMENT 等 ~- [ ] 生成常量声明，如：FOUNDATION_EXPORT double const foo;~ ~- [ ] 生成函数声明，如 FOUNDATION_EXPORT NSObject * _Nullable NXReadNSObjectFromCoder(NSCoder *decoder) API_DEPRECATED("Not supported", macos(10.0,10.5), ios(2.0,2.0), watchos(2.0,2.0), tvos(9.0,9.0));~
- [ ] （可能包含上面的问题）解决 flutter format 后的所有 Dart 语法报错问题
解析报错问题：

[x] NSBundle.h 报错 line 245:109 no viable alternative at input 'FOUNDATION_EXPORT NSNotificationName const NSBundleResourceRequestLowDiskSpaceNotification API_AVAILABLE(ios(9.0'
[x] NSCompoundPredicate.h, NSData.h 报错 line 11:64 extraneous input '<' expecting {';', ','}
[x] NSCompoundPredicate.h 报错 line 34:0 mismatched input '+' expecting '@end'
[x] NSCompoundPredicate.h 报错 line 34:80 extraneous input ')' expecting {'BOOL', 'Class', 'bycopy', 'byref', 'id', 'IMP', 'in', 'inout', 'oneway', 'out', 'Protocol', 'SEL', 'self', 'super', 'atomic', 'nonatomic', 'retain', '__autoreleasing', '__block', '__bridge_retained', '__bridge_transfer', '__covariant', '__contravariant', '__deprecated', '__kindof', '__unused', NULL_UNSPECIFIED, NULLABLE, NONNULL, 'null_resettable', 'NS_INLINE', 'NS_ENUM', 'NS_OPTIONS', 'assign', 'copy', 'getter', 'setter', 'strong', 'readonly', 'readwrite', 'weak', 'unsafe_unretained', 'IBOutlet', 'IBOutletCollection', 'IBInspectable', 'IB_DESIGNABLE', IDENTIFIER, LP}
[x] NSCompoundPredicate.h 报错 line 34:95 missing ';' at 'NS_SWIFT_NAME'
[x] NSException.h 报错 line 79:39 mismatched input '(' expecting ';'

内存问题：

[x] 目前针对单个大文件的 workaround 为提升老生代内存上限，多个文件开多线程并行可 fix
