Declare a C heap allocator.

Parameters

[in,out]	allocator_ptr	a pointer to an allocator that will be initialized to point to the one statically declared by the macro
[in]	allocator_name_symb	a unique symbol name that will be used as a name suffix for the statically declared data
[in]	block_count	the number of blocks
[in]	block_size	the size of each block
