[xml] Group fixes for GL_ATI_fragment_shader

[SunSerega]

The GL_ATI_fragment_shader extension had 4 of its enum groups defined, 3 of them never used.
I was fixing them as part of #520. But then I noticed how much more is missing and decided to add the rest of the groups.
I know this extension is outdated, but I don't want to leave it still half-baked after my changes.

From the spec, here are lists of which function takes what enums:

# ColorFragmentOp[%N%]ATI
	dst: REG_0_ATI
=	dstMod: NONE, 2X_BIT_ATI, 4X_BIT_ATI, 8X_BIT_ATI, HALF_BIT_ATI, QUARTER_BIT_ATI, EIGHTH_BIT_ATI, SATURATE_BIT_ATI
=	dstMask: NONE, RED_BIT_ATI, GREEN_BIT_ATI, BLUE_BIT_ATI
	argN: REG_0_ATI, CON_0_ATI, ZERO, ONE, PRIMARY_COLOR_ARB, SECONDARY_INTERPOLATOR_ATI
	argNRep: NONE, RED, GREEN, BLUE, ALPHA
=	argNMod: 2X_BIT_ATI, COMP_BIT_ATI, NEGATE_BIT_ATI, BIAS_BIT_ATI
# ColorFragmentOp1ATI
	op: MOV_ATI
# ColorFragmentOp2ATI
	op: ADD_ATI, MUL_ATI, SUB_ATI, DOT3_ATI, DOT4_ATI
# ColorFragmentOp3ATI
	op: MAD_ATI, LERP_ATI, CND_ATI, CND0_ATI, DOT2_ADD_ATI
	
# AlphaFragmentOp[%N%]ATI
	dst: REG_0_ATI
=	dstMod: NONE, 2X_BIT_ATI, 4X_BIT_ATI, 8X_BIT_ATI, HALF_BIT_ATI, QUARTER_BIT_ATI, EIGHTH_BIT_ATI, SATURATE_BIT_ATI
	argN: REG_0_ATI, CON_0_ATI, ZERO, ONE, PRIMARY_COLOR_ARB, SECONDARY_INTERPOLATOR_ATI
	argNRep: NONE, RED, GREEN, BLUE, ALPHA
=	argNMod: 2X_BIT_ATI, COMP_BIT_ATI, NEGATE_BIT_ATI, BIAS_BIT_ATI
# AlphaFragmentOp1ATI
	op: MOV_ATI
# AlphaFragmentOp2ATI
	op: ADD_ATI, MUL_ATI, SUB_ATI, DOT3_ATI, DOT4_ATI
# AlphaFragmentOp3ATI
	op: MAD_ATI, LERP_ATI, CND_ATI, CND0_ATI, DOT2_ADD_ATI
	
# PassTexCoordATI
	dst: REG_0_ATI
	coord: REG_0_ATI, TEXTURE0_ARB
=	swizzle: SWIZZLE_STR_ATI, SWIZZLE_STQ_ATI, SWIZZLE_STR_DR_ATI, SWIZZLE_STQ_DQ_ATI
	
# SampleMapATI
	dst: REG_0_ATI
	interp: REG_0_ATI, TEXTURE0_ARB
=	swizzle: SWIZZLE_STR_ATI, SWIZZLE_STQ_ATI, SWIZZLE_STR_DR_ATI, SWIZZLE_STQ_DQ_ATI
	
# SetFragmentShaderConstantATI
	dst: CON_0_ATI

= denotes groups that existed before my changes.

In the end, the groups of this extension are:

# FragmentShaderDestMaskATI
	NONE, RED_BIT_ATI, GREEN_BIT_ATI, BLUE_BIT_ATI
	ColorFragmentOp[%N%]ATI: dskMask
	
# FragmentShaderDestModMaskATI
	NONE, 2X_BIT_ATI, 4X_BIT_ATI, 8X_BIT_ATI, HALF_BIT_ATI, QUARTER_BIT_ATI, EIGHTH_BIT_ATI, SATURATE_BIT_ATI
	ColorFragmentOp[%N%]ATI: dstMod
	AlphaFragmentOp[%N%]ATI: dstMod

# FragmentShaderColorModMaskATI
	2X_BIT_ATI, COMP_BIT_ATI, NEGATE_BIT_ATI, BIAS_BIT_ATI
	ColorFragmentOp[%N%]ATI: argNMod
	AlphaFragmentOp[%N%]ATI: argNMod

# SwizzleOpATI
	SWIZZLE_STR_ATI, SWIZZLE_STQ_ATI, SWIZZLE_STR_DR_ATI, SWIZZLE_STQ_DQ_ATI
	PassTexCoordATI: swizzle
	SampleMapATI: swizzle

# FragmentShaderRegATI
	REG_0_ATI
	ColorFragmentOp[%N%]ATI: dst
	AlphaFragmentOp[%N%]ATI: dst
	PassTexCoordATI: dst
	SampleMapATI: dst

# FragmentShaderConATI
	CON_0_ATI
	SetFragmentShaderConstantATI: dst

# FragmentShaderGenericSourceATI
	REG_0_ATI, CON_0_ATI, ZERO, ONE, PRIMARY_COLOR_ARB, SECONDARY_INTERPOLATOR_ATI
	ColorFragmentOp[%N%]ATI: argN
	AlphaFragmentOp[%N%]ATI: argN

# FragmentShaderTextureSourceATI
	REG_0_ATI, TEXTURE0_ARB
	PassTexCoordATI: coord
	SampleMapATI: interp

# FragmentShaderValueRepATI
	NONE, RED, GREEN, BLUE, ALPHA
	ColorFragmentOp[%N%]ATI: argNRep
	AlphaFragmentOp[%N%]ATI: argNRep

# FragmentOp1ATI
	MOV_ATI
	ColorFragmentOp1ATI: op
	AlphaFragmentOp1ATI: op

# FragmentOp2ATI
	ADD_ATI, MUL_ATI, SUB_ATI, DOT3_ATI, DOT4_ATI
	ColorFragmentOp2ATI: op
	AlphaFragmentOp2ATI: op

# FragmentOp3ATI
	MAD_ATI, LERP_ATI, CND_ATI, CND0_ATI, DOT2_ADD_ATI
	ColorFragmentOp3ATI: op
	AlphaFragmentOp3ATI: op

Ancient history but seems reasonable

@rpatlega if you're happy with this I can approve for merge.

AMD is good for this change.
