timer: Clean up timer initializers

Over time, timer initializers became messy with unnecessarily
duplicated code which are inconsistently spread across timer.h and
timer.c.

This patch cleans up timer initializers.

* timer.c::__init_timer() is renamed to do_init_timer().

* __TIMER_INITIALIZER() added.  It takes @flags and all initializers
  are wrappers around it.

* init_timer[_on_stack]_key() now take @flags.

* __init_timer[_on_stack]() added.  They take @flags and all init
  macros are wrappers around them.

* __setup_timer[_on_stack]() added.  It uses __init_timer() and takes
  @flags.  All setup macros are wrappers around the two.

Note that this patch doesn't add missing init/setup combinations -
e.g. init_timer_deferrable_on_stack().  Adding missing ones is
trivial.
