Windows: allow cancelling long mount operations
...
Add a root-driver abort IOCTL that bypasses the mount control mutex and sets cooperative KDF abort flags for the active mount.
Restrict abort requests to privileged callers or to the user that initiated the pending mount, and retry early wait-dialog cancel requests until the driver has registered the cancellable mount context.
Wire the wait dialog Cancel button to send the abort request through a fresh driver handle, and propagate ERR_USER_ABORT through header/cache processing.
Add a /cancelmount command-line switch that sends the same abort request without displaying UI, so users can cancel hidden-wait-dialog mount operations from another process.

Windows driver: simplify TCSleep to use KeDelayExecutionThread
...
Replace timer-based TCSleep (which allocated a KTIMER and waited on it) with an
implementation that calls KeDelayExecutionThread. This removes dynamic allocation
and kernel timer usage to simplify the code and reduce resource overhead.
Adds an IRQL <= APC_LEVEL assertion and documents the requirement.
This is safe because TCSleep is always called from code that runs at PASSIVE_LEVEL

Windows Driver: Make max work items count configurable. Increase default to 1024. Queue write IRPs.
...
- Made the maximum work items count configurable to allow flexibility based on system needs.
- Increased the default value of max work items count to 1024 to better handle high-throughput scenarios.
- Queue write IRPs in system worker thread to avoid potential deadlocks in write scenarios.

Windows Driver: Add registry settings to control driver internal encryption queue Under HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\veracrypt: - VeraCryptEncryptionFragmentSize (REG_DWORD): size of encryption data fragment in KiB. Default is 256. - VeraCryptEncryptionIoRequestCount (REG_DWORD): maximum number of parallel I/O requests. Default is 16. - VeraCryptEncryptionItemCount (REG_DWORD): maximum number of encryption queue items processed in parallel. Default is 8.

Windows Security: Add new entry point in driver that allows emergency clearing of all encryption keys from memory. This entry point requires administrative privileges and it will caused BSDO when system encryption is active. It can be useful for example to applications that monitors physical access to the machine and which need to erase sensitive key material from RAM when unauthorized access is detected.
