mesa: add numLevels, numSamples to Driver.TestProxyTexImage()

Browse Source 
So that the function can work properly with glTexStorage(), where we know
how many mipmap levels there are.  And so we can compute storage for MSAA
textures.

Also, remove the obsolete texture border parameter.

A subsequent patch will update _mesa_test_proxy_teximage() to use these
new parameters.
