Remove --win64-unwinding-info flag and always generate unwind info on Win/x64

The generation of unwind info to enable stack walking on Windows/x64
(https://chromium-review.googlesource.com/c/v8/v8/+/1469329) was implemented
behind a temporary flag, in order to coordinate these changes with the
corresponding changes in Chromium.

The required changes to Chromium
(https://chromium-review.googlesource.com/c/chromium/src/+/1474703) have also
been merged, so we can now remove the flag and enable the generation of stack
unwinding info by default on Windows/x64.
