aarch64_be SIGILL in resume_until_execution_reaches()

At the following place:

https://github.com/frida/frida-core/blob/535bb66d6355c5bba5dfdc412af2130c4863bba2/src/linux/frida-helper-backend.vala#L1938C36-L1938C36

uint32 breakpoint_val = 0xd4200000U; needs byte order reversed for aarch64_be as instructions are always little endian. Any idea how to do this elegantly from frida-helper-backend.vala? Before this code was moved to vala I might have tried GUINT32_TO_LE() but I don't know if there's a useful equivalent in vala.

FYI arm (32-bit) BE8 is broken for similar reasons. I'm patching an internal fork for now so I can get things working for our targets.
