[libunwind] Support DW_CFA_remember/restore_state without heap allocation.
This patch just reorganises the code to make possible to use alloca
instead of malloc. This makes possible to use `.cfi_remember_state`/`.cfi_restore_state` on
platforms without heap allocation.
Also it will be safe to backtrace/unwind faults related to the allocator behind malloc.
`_LIBUNWIND_REMEMBER_HEAP_ALLOC ` option reenables the heap usage for `.cfi_remember_state`/`.cfi_restore_state`.
Define _LIBUNWIND_REMEMBER_STACK_ALLOC to force stack allocation.
