Subject: x86/traps: Split trap numbers out in a separate header
Git-commit: 877f183f83cc33b1b09313b9c18ab7ee5abda44f
Patch-mainline: v5.8-rc1
References: jsc#SLE-14337
So they can be used in ASM code. For this it is also necessary to convert
them to defines. Will be used for the rework of the entry code.
