Hitting a BOSD in a Windows guest in Virtualbox 6 leads to calling
`DBGFR3ReportBugCheck`, which leads to the following error since it is
unimplemented in our port:
```
Error: DBGFR3ReportBugCheck: DBGFR3ReportBugCheck called, not implemented, eip=0x1a5c4e4
```
Including the actual method from Virtualbox 6 enables logging
diagnostics for the Windows Blue Screen of Death (BSOD).
To see Blue Screen logging output, enable "dbgf" and "gim" logging
via the `VBOX_LOG` following environment variable in the vbox6 runtime
config.
When manually triggering a BSOD in the Windows guest, this should
produce the following logging diagnostics:
```
GIM: HyperV: Guest indicates a fatal condition! P0=0xe2 P1=0x0 P2=0x0 P3=0x0 P4=0x0
GIMHv: BugCheck e2 {0, 0, 0, 0}
MANUALLY_INITIATED_CRASH
```
Fixes #5099
