90642dc130 Fix get_return_object() of task/lazy_task promise under clang. 
Clang didn't seem to allow conversion from get_return_object()
return value to coroutine return value via explicit constructor.

Now get_return_object() explicitly constructs task/lazy_task object
rather than returning coroutine_handle. This required moving
method definition to below task/lazy_task class definition.

5ea2225efe Use <experimental/filesystem> instead of <filesystem> 
Clang's libc++ doesn't yet have a <filesystem> header.

29ce3d2727 Avoid use of CALLBACK as template parameter name. 
Windows.h defines CALLBACK as a macro which causes compile-errors
if included before the cancellation_registration.hpp header.

d269d1df27 Remove set_exception() methods from promise types. 
MSVC 2015 isn't supported any more so we should be able to rely on
unhandled_exception() being supported.

8cf10ce184 Add async file I/O support for Win32 platform. 
- Adds file, readable_file, writable_file, read_only_file,
  write_only_file and read_write_file classes.
- Adds file_share_mode, file_open_mode, file_buffering_mode enums.
- Supports async read/write but only synchronous open for now.
- Removes support for VS 2015 since implementation makes use of
  std::optional which is only available in VS 2017.

49eb9d62b5 Conditionally disable set_exception() methods for newer MSVC versions. 
Newer MSVC versions complain if you have both unhandled_exception()
and set_exception() defined on your promise_type.

10fc3b1ecd Fix cppcoro::make_shared_task() for task<void> case. 
Work around bug in MSVC by providing special-case overload of
make_shared_task() for task<void>. Add test for this.

9007c7bf92 Make cancellation_registration more efficient. 
Now keeps track of approximate number of free slots in a registration
chunk so that entire chunks can often be skipped when scanning for
free slots. Also, starts scanning at a position within the chunk based
on the number of free slots. This should handle typical LIFO cases
more efficiently when accessed from a single thread.

Ideas have been borrowed from .NET CancellationToken implementation.
