[lldb] [Process/Utility] Fix value_regs/invalidate_regs for ARM

Fix incorrect values for value_regs, and incomplete values for
invalidate_regs in RegisterInfos_arm.  The value_regs entry needs
to list only one base (i.e. larger) register that needs to be read
to get the value for this register, while invalidate_regs needs to list
all other registers (including pseudo-register) whose values would
change when this register is written to.

7a8ba4ff fixed a similar problem
for ARM64.
