UefiCpuPkg/CpuExceptionHandler: Make XCODE5 changes toolchain specific
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2340
Commit 2db0ccc2d7fe ("UefiCpuPkg: Update CpuExceptionHandlerLib pass
XCODE5 tool chain") introduced binary patching into the exception handling
support. CPU exception handling is allowed during SEC and this results in
binary patching of flash, which should not be done.
Separate the changes from commit 2db0ccc2d7fe into an XCODE5 toolchain
specific file, Xcode5ExceptionHandlerAsm.nasm, and create a new SEC INF
file for the XCODE5 version of CpuExceptionHandlerLib.
Since binary patching is allowed when running outside of flash, switch
the Dxe, Pei and Smm versions of the CpuExceptionHandlerLib over to use
the Xcode5ExceptionHandlerAsm.nasm file to retain current functionality.
