Title:
  Set MIPS MSA in ELF Auxiliary Vectors

Status in QEMU:
  In Progress

Bug description:
  The MIPS MSA feature is currently not set in the ELF auxiliary vector.

  That is, querying the AT_HWCAP key of the ELF auxiliary vectors for a
  MIPS CPU that has the MSA feature should return a value that has the
  second bit [0] set.

  From [0], `HWCAP_MIPS_MSA` is defined to `1 << 1`.
