mesa: rework texture size error checking
There are two aspects to texture image size checking:
1. Are the width, height, depth legal values (not negative, not larger
than the max size for the mipmap level, etc)?
2. Is the texture just too large to handle? For example, we might not be
able to really allocate memory for a 3D texture of maxSize x maxSize x
maxSize.
Previously, we did (1) via the ctx->Driver.TestProxyTextureImage() hook
but those tests are really device-independent. Now we do (2) via that
hook since the max texture memory and texture shape are device-dependent.
Also, (1) is now done outside the general texture parameter error checking
functions because of the special interaction with proxy textures. The
recently introduced PROXY_ERROR token is removed.
The teximage() and copyteximage() functions are bit simpler now (less
if-then nesting, etc.)
