Core: Use the stack region in the linker file
Using array to store stack will consume lots of memory. To let all
platforms have enough RAM space, change to use every partition's own
stack from linker script.
- Use tfm_spm_partition_memory_data_t to store memory information
instead of unified stack size in level 1.
- Initialize partition thread stack range with its own size.
- Remove the unified stack size member from the spm_partition_desc_t
structure for level 1.
- Make tfm_spm_partition_get_stack_bottom() and
tfm_spm_partition_get_stack_top() functions available for all levels.
- Remove tfm_spm_partition_get_stack_base_ext() and
tfm_spm_partition_get_stack_limit_ext() functions.
