feat: support non-continuous memory regions
The multiple non-continuous memory regions are supported when the macro LOSCFG_MEM_MUL_REGIONS is enabled. The array of the type LOS_MEM_REGION should be defined, and each array element defines the start address and the length for each memory regions, \ begining from the lower address to the higher memory address. close #I43XOP Signed-off-by: kenneth <zhushangyuan@huawei.com>

* @attention
|

* <ul>
|

* <li>If the starting address of a memory pool is specified, the start address of the non-continuous memory regions should be

* greater than the end address of the memory pool.</li>
|

* <li>The multiple non-continuous memory regions shouldn't conflict with each other.</li>
|

* </ul>

||||
*
|
||||
* @param pool [IN] The memory pool address. If NULL is specified, the start address of first memory region will be
|
||||
* initialized as the memory pool address. If not NULL, it should be a valid address of a memory pool.
|
||||
* @param memRegions [IN] The LosMemRegion array that contains multiple non-continuous memory regions. The start address
|
||||
* of the memory regions are placed in ascending order.
|
||||
* @param memRegionCount [IN] The count of non-continuous memory regions, and it should be the length of the LosMemRegion array.
