core: arm: sm: optimize padding in struct sm_ctx
Removes redundant padding in struct sm_ctx and sub-structs with regards
to CFG_SM_NO_CYCLE_COUNTING. Saves 4 bytes per core if
CFG_SM_NO_CYCLE_COUNTING is defined.
Removes assumptions in monitor assembly code about where the padding in
struct sm_ctx is located.
Adds compile time asserts are added to check that struct sm_ctx is
properly aligned.
