Add a PcdEmulatorLazyLoadSymbols that allows non-lazy symbol loading. The problem with lazy symbol loading is it only happens after you hit a breakpoint. This means you can't add breakpoints from the GUI and have them hit, this requires symbols being loaded as modules load so the breakpoints can get resolved.

Added arguments to SecGdbScriptBreak() to enable lldb python symbol load/unload script.
