  [lsan] Process non-suspended threads (#112807)

For such threads we have no registers, so no exact
stack range, and no guaranties that stack is mapped
at all.

To avoid crashes on unmapped memory,
 `MemCpyAccessible` copies intersting range into
 temporarily buffer, and we search for pointers there.
