[PULL 1/1] tracetool: removed the unused vcpu property

[Stefan Hajnoczi]

From: Tanish Desai <tanishdesai37@gmail.com>

The vcpu property is no longer used in these backends. Removing it avoids
unnecessary checks and simplifies the code generation for these trace
backends.

  log: make '-msg timestamp=on' apply to all qemu_log usage (2025-07-24 10:12:21 -0400)

----------------------------------------------------------------
Pull request

This commit is still worth having in QEMU 10.1 for the all-round improvements
made (consistent timestamping, binary size reduction, header pollution cleanup)
even if it's debatable whether this is a bug fix.
