[core] switch to async I/O for image writing

* Combined with the increase in buffer size from previous commits, this
  should help us get close to a device's maximum write speed.
* Also add async write support to winio.h
* Also increase the buffer size for bad blocks check operations

[checksum] improve performance by switching to async I/O

Yes!!! We are finally *much* faster than 7-zip for SHA-256, even though
we are also computing MD5 and SHA-1 in parallel. Here are some averaged
comparative results, against the 5.71 GB Win10_20H2_EnglishInternational_x64.iso
(SHA-256 = 08535b6dd0a4311f562e301c3c344b4aefd2e69a82168426b9971d6f8cab35e1):
* Windows' PowerShell Get-FileHash: 48s
* 7-zip's SHA-256                 : 31s
* Rufus (64-bit release version)  : 23s
