[Bug runtime/11671] New: Allocate __stp_tf_vma_entry dynamically

Currently the __stp_tf_vma_free_list_items array list is allocated staticly with
the value of TASK_FINDER_VMA_ENTRY_ITEMS in runtime/task_finder_vma.c.

Setting this to some arbitrary default is not very efficient, since this is
often way too much for tracking a single process, but often too little when
tracking the whole system.

It would be good if new list items could be allocated (and deallocated?)
dynamically. In theory this should be possible since the table should only be
updated with new items from a safe context (but can be read/searched from any
context).
