Move qemuMonitorEscape + migrate status enum into shared monitor code

The qemuMonitorEscape() method, and the VIR_ENUM for migration
status will be needed by the JSON monitor too, so move that code
into the shared qemu_monitor.c file instead of qemu_monitor_text.c

* src/qemu/qemu_monitor.h: Declare qemuMonitorMigrationStatus enum
  and qemuMonitorEscapeArg and qemuMonitorEscapeShell methods
* src/qemu/qemu_monitor.c: Implement qemuMonitorMigrationStatus enum
  and qemuMonitorEscapeArg and qemuMonitorEscapeShell methods
* src/qemu/qemu_monitor_text.c: Remove above methods/enum
