rsun3 e7c4ef5ed4 DuetPkg BootSector: fix bugs in .S files so that 32-bit and 64-bit DUET can boot to Shell with boot sector binaries built by GCC.
There is also a bug in bs32.asm/bs32.S that the space between the code and the 0xAA55 ending signature is not enough to hold the 2 debug strings. It is fixed by shortening the strings.

rsun3 3a4b9eba07 DuetPkg BootSector:
Update start.asm(S)/start16.asm(S)/start32.asm(S)/efi32.asm(S) under DuetPkg\BootSector to follow the IA32 recommendations on switching to protected mode: Immediately following the MOV CR0 instruction, execute a far JMP or far CALL instruction. (This operation is typically a far jump or call to the next instruction in the instruction stream.)

klu2 e88f305671 This patch includes:
1) Use the binaries of boot sector directly instead of building it. Because the code of boot sector will be modified rarely and it is native code.
2) Correct the shell binary file path which is changed by recently.
