The CPU fallback for the compute renderer is contained in a separate
module for space reasons, but the CPU binaries must exactly match the
compute programs. However, there is no way to express that constraint
in go.mod.
This change generates hashes of every compute program so that a
following change can verify the CPU binaries match the programs.

The recent changes to the compute shaders have fixed all errors
previously reported by fxc. Switch from dxc to fxc to target shader
model 5.0, supported by Direct3D 11.
Because we know dxc must be available, always build compute shaders even
though the result is not yet used.

Literal strings are a more compact than literal byte slices. A future
change will switch to go:embed to save even more space.

There are no longer any importers of package backend outside of
gioui.org/gpu. Move it internally, and rename it to the slightly more
specific "driver" while we're at it.

The convert program is only used by the shaders from package gpu, and
we're about to make the backend package imported by the program internal
to package gpu. Move the converter below package gpu.
