debug: EXCEPTION_STACK_TRACE should depend on arch Kconfigs

Fix the dependencies of `CONFIG_EXCEPTION_STACK_TRACE`:
- Architecture-specific Kconfig, i.e.
  `X86_EXCEPTION_STACK_TRACE`, will be enabled automatically
  when all the dependencies are met.
- `EXCEPTION_STACK_TRACE` depends on architecture-specific
  Kconfig to be enabled.
- The stack trace implementations should be compiled only if
  user enables `CONFIG_EXCEPTION_STACK_TRACE`.
