MIPS: Fix XPA base and Virtualization ASE instruction handling

Correct a commit 7d64c587c1 ("Add support for the MIPS eXtended
Physical Address (XPA) ASE.") bug, causing XPA base and Virtualization
ASE instructions to be wrongly always enabled with the selection of the
MIPS32r2 or higher ISA.

For example this source assembles successfully as shown below:

$ cat xpa.s
	mfhc0	$2, $1
$ as -32 -mips32 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32 (mips32) `mfhc0 $2,$1'
$ as -32 -mips32r2 -o xpa.o xpa.s
$ objdump -d xpa.o

xpa.o:     file format elf32-tradbigmips

Disassembly of section .text:

00000000 <.text>:
   0:	40420800 	mfhc0	v0,c0_random
	...
$

To address this issue remove the I33 (INSN_ISA32R2) marking from all XPA
instructions in the opcode table.  Additionally, for XPA Virtualization
ASE instructions implement an XPAVZ (ASE_XPA_VIRT) combination ASE flag
and use it in place of IVIRT|XPA (ASE_VIRT|ASE_XPA).

Now the same source is correctly rejected unless the `-mxpa' option is
also used:

$ as -32 -mips32r2 -o xpa.o xpa.s
xpa.s: Assembler messages:
xpa.s:1: Error: opcode not supported on this processor: mips32r2 (mips32r2) `mfhc0 $2,$1'
$ as -32 -mips32r2 -mxpa -o xpa.o xpa.s
$

Add test cases for XPA base and XPA Virtualization ASE instructions.
