[OpenMP][AArch64] Fix frame pointer save in microtask (#165313)

Browse Source 
When OMPT is enabled, the stack pointer was not saved to frame pointer
register immediately after storing the frame pointer to the stack.
Therefore the frame pointers did not constitute a proper chain.
Fixes [#163352](https://github.com/llvm/llvm-project/issues/163352)
