Adds 64-bit (x86_64) support to libpayload's exception handler, previously limited to x86_32. Ensures `exception_init_asm` is called when building with LP_ARCH_X86_64 Kconfig. BUG=b:336265399 TEST=Successful build and boot of google/rex and google/rex64 on ChromeOS. Verified correct x86_64 exception handling by triggering "Debug Exception" using firmware-shell as below: firmware-shell: mm.l -0 Debug Exception Error code: n/a REG_IP: 0x0000000030023e9f REG_FLAGS: 0x0000000000000046 REG_AX: 0x0000000000000009 REG_BX: 0x0000000000000000 REG_CX: 0x0000002000000000 REG_DX: 0x0000000000000001 REG_SP: 0x0000000034072ec0 REG_BP: 0x0000000000000009 REG_SI: 0x0000000000000029 REG_DI: 0x0000000034072eef REG_R8: 0x0000000000000009 REG_R9: 0x0000000000000000 REG_R10: 0x0000000000000000 REG_R11: 0x0000000034072d70 REG_R12: 0x0000000000000004 REG_R13: 0x0000000000000001 REG_R14: 0x0000000034072ee6 REG_R15: 0x0000000000000004 CS: 0x0020 DS: 0x0000 ES: 0x0000 SS: 0x0018 FS: 0x0018 GS: 0x0050 Dumping stack: 0x340730c0: 3003c32e 00000000 ... 00000000 00000000 0x340730a0: 30034bc6 00000000 ... 0000002a 00000000 0x34073080: 34073234 00000000 ... 00002e65 00000000 ... ... 0x34072ee0: 340730ed 30300000 ... 34073000 00000000 0x34072ec0: 34072ed8 00000000 ... 00000000 00000008 Ready for GDB connection.
