[vk, ogl] Remove dedicated precomputed swizzle table; use shorter inline table in block_linear swizzle shaders (#4146)
old table = 64 * 8 * sizeof(u32) = 512 * 4 = 4096 bytes
new table = 8 * sizeof(u32) = 8 * 4 = 32 bytes
the expression
```glsl
return ((pos & 0x0180) >> 1)
| ((pos & 0x0040) >> 2)
| ((pos & 0x0020) << 3)
| ((pos & 0x0010) << 1)
| ((pos & 0x000f) << 0);
```
is equivalent for generating the table but idk if we'd want that
