ntdll: Fix more corner cases for arm64 packed info unwinding.
Make sure to restore sp from fp for CR == 3.
Fix unwinding of partial prologues/epilogues - the previous logic had an off-by-one for the pos/skip handling; fix a few more corner cases with odd number of saved registers.
Functions with the H flag set (saving x0-x7 on the stack) should be considred having 4 nops (for the instructions saving the registers) in the prologue for unwind purposes. When unwinding through a partial epilogue, the same 4 nops should also be considered to be there (even though no sane epilogue would restore the registers there) based on how windows handles partial epilogue unwinding in those cases.
Uncomment prologue/epilogue cases in an existing test and add tests for many more cases.
