Revert "msvs/ninja win: Fix support for ImageHasSafeExceptionHandlers"

This patch is being reverted because it caused build errors in chromium when
attempting a gyp roll.

Here's an example error:
LINK : fatal error LNK1246: '/SAFESEH' not compatible with 'x64' target
machine; link without '/SAFESEH'

Bonus points for also adding a test that would've caught this problem.
