The error_report function can include the guest name in any

This introduces support for a "workload name" in the new
messages API, which in the case of system emulators will
be the guest name. The possibility of defining a workload
name for other binaries is left as an exercise for the
future.
This change has no impact on the output of the error_report
function, but will change the qemu_log function. This can
be easily seen with the 'log' trace backend, and how it is
now more closely matching error_report output.
Before:
# qemu-system-x86_64 -msg guest-name=on -name blah -object
tls-creds-x509,id=t0,dir=fish -d 'trace:qcrypto*'
qcrypto_tls_creds_x509_load TLS creds x509 load creds=0x55b3af3fd870 dir=fish
qcrypto_tls_creds_get_path TLS creds path creds=0x55b3af3fd870
filename=ca-cert.pem path=<none>
blah qemu-system-x86_64: Unable to access credentials fish/ca-cert.pem: No
such file or directory
After:
# qemu-system-x86_64 -msg guest-name=on -name blah -object
tls-creds-x509,id=t0,dir=fish -d 'trace:qcrypto*'
blah qcrypto_tls_creds_x509_load TLS creds x509 load creds=0x55b3af3fd870
dir=fish
blah qcrypto_tls_creds_get_path TLS creds path creds=0x55b3af3fd870
filename=ca-cert.pem path=<none>
blah qemu-system-x86_64: Unable to access credentials fish/ca-cert.pem: No
such file or directory
