microkernel: introduce support for private memory maps

This enable defining memory maps in source code in addition to
defining in MDEF files. This introduces the macro
DEFINE_MEM_MAP(mem_map_name, ...). The memory maps created this
way are the same, in functionality, as those defined in MDEF
files. They can be manipulated by the standard microkernel
memory map APIs.

Define the memory map using:

  DEFINE_MEM_MAP(mem_map1, blocks, block_size);

and "mem_map1" can be used, for example:

  task_mem_map_alloc(mem_map1, ...);

or,

  task_mem_map_free(mem_map1, ...);

etc.

To use the memory map defined in another source file, simply add:

extern const kmemory_map_t mem_map1;

to the desired C or header file.
