utils.bbclass/multilib.class: Added misc supporting functions.

Browse Source 
1. Added variable MULTILIB_VARIANTS to store all the instance variants
for multilib extend.

2. Added function all_multilib_tune_values to collect the variable
values for all multilib instance.

3. multilib bbclass handler will save the orignal value of all variables
defined in MULTILIB_SAVE_VARNAME.
