  Log Message:
  -----------
  [hip][cuda] Enable extended lambda support on Windows.

- On Windows, extended lambda has extra issues due to the numbering
  schemes are different between the host compilation (Microsoft C++ ABI)
  and the device compilation (Itanium C++ ABI. Additional device side
  lambda number is required per lambda for the host compilation to
  correctly mangle the device-side lambda name.
- A hybrid numbering context `MSHIPNumberingContext` is introduced to
  number a lambda for both host- and device-compilations.
