swr: Report format max_samples=1 to maintain support for "fake" msaa.

Accompanying patch "st/mesa: only try to create 1x msaa surfaces for
'fake' msaa" requires driver to report max_samples=1 to enable "fake"
msaa. Previously, 0 and 1 were treated equivalently in st_init_extensions()
and either could enable "fake" msaa.

This patch raises the swr default msaa_max_count from 0 to 1, so that
swr_is_format_supported will report max_samples=1.

Real msaa can still be enabled by exporting SWR_MSAA_MAX_COUNT with a
pow2 value between 2 and 16.

This patch is necessary to prevent an OpenSWR regression resulting from
the st/mesa patch.

st/mesa: only try to create 1x msaa surfaces for "fake" msaa drivers

For software drivers where we want "fake" msaa support for GL 3.x, we
treat 1 sample as being msaa.

For drivers with real msaa support, start format probing at 2x msaa.
For drivers with fake msaa support, start format probing at 1x msaa.

This also tweaks the MaxSamples code in st_init_extensions() so that
we use MaxSamples=1 for fake msaa.  This allows the format proble loops
to run at least one iteration.

This fixes a llvmpipe/VTK regression from commit 6839d3369905eb02151.
And for drivers with fake msaa support, calls such as

When we blit data into a buffer object, we may need to invalidate any

For example, if the buffer object is bound as a vertex buffer, we need
to invalidate the vertex fetch cache.

While this flushing was missing, it usually happened implicitly for
non-obvious reasons: we're usually on the render ring, and calling
intel_emit_linear_blit() would require switching to the BLT ring,
causing an implicit flush.  This likely provoked the kernel to do
PIPE_CONTROLs on our behalf.  Although, Gen4-5 wouldn't have this
