Since we can't properly resolve the depth buffer, we have to use one
samole, so use the sample 0 and not a random value from tc.z.

The extension declaration must come before the precision definition, and
in GLES we have to emit the OES extension instead of the ARB extension.

When running a GL 2.1 program in that guest on a GLES host that uses 1D
textures then the emitted shaders must not declare 1D sampler, since they
are not supported. Instead, use 2D samplers since 1D textures are emulated
by 2D textures, and also fix the texture shader call.

Update the GL blit code to support blitting for multisample textures,
for both normalized and integer color formats.
The minimum GLSL ES version in the shaders is also raised to 3.1, since
GLSL ES 3.0 doesn't support multisample textures.

Update the blit shader creation code to take the destination format
swizzle into account. This involves inverting the swizzle information
and using the inverted swizzle to reorder the texel components in the
shader. The new swizzle code also removes the need for having a special
case if the destination format uses emulated alpha.
This commit temporarily removes the VIRGL_FORMAT_R8G8B8X8_UNORM special
case. Improved support for it, and other similar "ignore alpha" cases,
is added back in an upcoming commit using appropriate swizzles.
At the moment we always recreate the shader in case we have a swizzle,
but a more efficient shader caching scheme could be devised to improve
this.
