Update GdbRun.sh to load symbols as modules are loaded and executed in the EmulatorPkg by executing a command each time the function SecGdbScriptBreak is executed. Set PcdEmulatorLazyLoadSymbols to FALSE to disable lazy symbol loading. With these changes, a break point can be set in any source file that is part of the EmulatorPkg build before the EmulatorPkg is executed. Signed-off-by: Michael D Kinney <michael.d.kinney@intel.com>
