[LLDB][MIPS] Fix offsets of all register sets and add MSA regset and FRE=1 mode support

This patch :

- Fixes offsets of all register sets for Mips.
- Adds MSA register set and FRE=1 mode support for FP register set.
- Separates lldb register numbers and register infos of freebsd/mips64 from linux/mips64.
- Re-orders the register numbers of all kinds for mips to be consistent with freebsd order of register numbers.
