rsx: Fixes

[kd-11]

#3710 broke github (detects no changes, 0 commits)

• Disables blit operations if the target will have a size of 0 in any dimension. Fixes blit engine crashing when GPU texture scaling is disabled.
• Bumps shader cache ver to 1.1. Vertex input declarations (unused since vertex rewrite) and texture sampling coord type (unnormalized vs normalized) no longer affect shader state and do not generate new shaders. Shader cache should generate fewer shaders in affected titles.
• Do not respect FENCx instructions as they seem to be an optimization hint. Respecting FENCx instructions can result in some hilariously broken shaders including entire shaders that are one big NOP

No change in Tales of Graces (skit blur, transparent black lines, half menu background)

accidently deleted log. just heads up for others doing testing, i saw no difference.

Jojo all star battle still has same issues but performance has increased by 1-2fps consistently! Would you know what is causing the inverted shadows?
