This commit implements registering unwind information for JIT functions on Windows so that the operating system can both walk and unwind stacks containing JIT frames. Currently this only works with Cranelift as lightbeam does not emit unwind information yet. This commit also resets the stack guard page on Windows for stack overflow exceptions, allowing reliable stack overflow traps. With these changes, all previously disabled test suite tests (not including the multi-value tests) on Windows are now passing. Fixes #291.
