  hw/char/riscv_htif: Convert HTIF_DEBUG() to trace events (2025-01-19 09:44:35 +1000)

----------------------------------------------------------------
Second RISC-V PR for 10.0

* Reduce the overhead for simple RISC-V vector unit-stride loads and stores
* Add V bit to GDB priv reg
* Add 'sha' support
* Add traces for exceptions in user mode
* Update Pointer Masking to Zjpm v1.0
* Add Smrnmi support
* Fix timebase-frequency when using KVM acceleration
* Add RISC-V Counter delegation ISA extension support
* Add support for Smdbltrp and Ssdbltrp extensions
* Introduce a translation tag for the IOMMU page table cache
* Support Supm and Sspm as part of Zjpm v1.0
* Convert htif debug prints to trace event
