component PSA: keep SVCHandler_main/tfm_pendsv_do_schedule symbol in LTO builds 

Add a "used" attribute to SVCHandler_main/tfm_pendsv_do_schedule to fix ARMC6 build with
the "-flto" flag.

This attribute, attached to a function/variable, means that code must be emitted
for the function even if it appears that the function is not referenced.
