GPU: Shader optimizations using inversesqrt and dead code removal

Chris Healy 7ea1260ef0 OpenGL: Fix GLES3 detection for Mesa/Panfrost Mali drivers 
The original code checked for "Mali" in GL_RENDERER and disabled GLES3
for all Mali GPUs, which was a workaround for bugs in ARM's proprietary
Mali driver. However, Mesa/Panfrost (open-source Mali driver) does not
have these bugs and should be allowed to use GLES3.

This patch:
- Adds GPU_VENDOR_MESA for identifying Mesa drivers via GL_VENDOR
- Changes the GLES3 ban to only apply when GL_VENDOR="ARM" (proprietary)
- Allows Mesa/Panfrost Mali GPUs to use GLES3 features

Expected behavior:
- ARM proprietary driver (GL_VENDOR="ARM"): GLES3 disabled (preserved)
- Mesa/Panfrost (GL_VENDOR="Mesa"): GLES3 enabled
- Other Mesa drivers: Unaffected

Related issues: #4078, #15413

Chris Healy 9ed5dcdc27 GPU: Use inversesqrt for light distance and half-vector calculations 
Replace length()/normalize() with inversesqrt() pattern for better
performance on mobile GPUs. The inversesqrt instruction is a single
hardware operation, while length() requires sqrt(dot()) and normalize()
requires inversesqrt internally plus a multiply.

Changes:
1. Light distance calculation:
   Before: distance = length(toLight); toLight /= distance;
   After:  distSq = dot(toLight, toLight);
           invDist = inversesqrt(distSq);
           distance = distSq * invDist;
           toLight *= invDist;

2. Specular half-vector normalization:
   Before: ldot = dot(normalize(toLight + vec3(0,0,1)), worldnormal);
   After:  halfVec = toLight + vec3(0,0,1);
           halfInvLen = inversesqrt(dot(halfVec, halfVec));
           ldot = dot(halfVec, worldnormal) * halfInvLen;

Also reuses distSq in attenuation calculation to avoid recomputing
distance*distance.

Offline shader compiler results (vertex shader with 4-light ubershader):

Mali (malioc):
  G31 (Bifrost): 44.90 -> 40.50 cycles (-9.8%)
  G52 (Bifrost): 14.97 -> 13.50 cycles (-9.8%)
  G310 (Valhall): 13.88 -> 12.88 cycles (-7.2%)
  G57 (Valhall):  7.60 ->  6.97 cycles (-8.3%)

PowerVR (Profiling Compilers):
  Series 8 GE8300: 322 -> 302 ALU cycles (-6.2%)
  Series 9 GM9445: 296 -> 280 ALU cycles (-5.4%)
  Series B BXM:    560 -> 540 instructions (-3.6%)
