Fix a memory layout issue when CFG_WITH_STMM_SP=y and CFG_WITH_PAGER=y.
Before this change were all StMM operation function handlers their
related resources being linked into the pager unpaged sections despite
they could be pageable. The reason is stmm_sp_ops is referenced in
helper function is_stmm_ctx() which is referenced in unpaged helper
function is_user_mode_ctx().
This change removes stmm_sp_ops reference pager constraint by using
an indirect reference in is_stmm_ctx().
Declare stmm_dump_state() in pager unpaged section and preserve
__rodata_unpaged attribute for stmm_sp_ops since ::dump_state
operation is called from unpaged context by abort_print_current_ts().
