See previous commit for justification. I decided to split these
refactors up into several independent commits to make it easier
to review and bisect, since they are all independent atomic changes.

I want to introduce operations like semiplanar reads, which would
possibly require a different number of over_read bytes per plane.
That aside, this is just a general cleanliness improvement.

The old x86 backend was the only backend that actually mutated the ops list.
With this gone, we can constify this parameter.

This allows constraining the set of available backends. This serves as a
better replacement for the "unstable" flag, which is a bit ambiguous. Allows
users to, for example, opt into the memcpy or x86 backend, while excluding
e.g. the upcoming JIT backends.

Allows the uops macro generation code to not actually compile any passes.
More generally, this could be used to e.g. test if an op list is supported by
a backend without actually creating the passes.
The `bool first` change is needed because the `input == prev` check no longer
works if we don't actually compiled any passes.

This will be used eventually when I rewrite checkasm/sw_ops to re-use the
code in ops_dispatch.c instead of hand-rolling the execution layer.

This function actually lives in ops_dispatch.c, and doesn't really make
sense in ops.h anymore. We should also move some stuff out of ops_internal.h,
which doesn't depend on any external ops stuff, here.
This allows the backend/compilation-related stuff to co-exist more nicely.

This is cheap to precompute and can be used as-is for gather-style horizontal
filter implementations.

This is more useful for tight loops inside CPU backends, which can implement
this by having a shared path for incrementing to the next line (as normal),
and then a separate path for adding an extra position-dependent, stride
multiplied line offset after each completed line.
As a free upside, this encoding does not require any separate/special handling
for the exec tail.

These were abstraction-violating in the first place. Good riddance.
This partially reverts commit c911295f09.

Allows compiled functions to opt out of the ops_dispatch execution harness
altogether and just get dispatched directly as the pass run() function.
Useful in particular for Vulkan.

This code is self-contained and logically distinct from the ops-related
helpers in ops.c, so it belongs in its own file.
Purely cosmetic; no functional change.
