[shader_recompiler] Add IAbs64 to prevent errors when using I2F with a 64-bit packed CBUF variant (#2918)

Browse source 
- Using I2F cbuf variant (packed 32x2 aka. U64)
- Code will call IAbs() if some conditions are met (signed + abs bit)
- Uh oh we don't have a variant for 64 bits!
- Fuck now we just made BAD ir code :(
