* Bump to vir-simd v0.4.0
* Replace gr::meta::simdize with vir::simdize.
* Replace gr::meta::simdize_size_v with ::size() on simdized types.
* "Document" that vir::transform can be used, where std::transform and
std::ranges::transform are documented.

Remove:
- invokeProcessOneWithOrWithoutOffset
- exact_argument_type
- can_processOne_with_offset_invoke_test
- can_processOne_simd_with_offset
- can_processOne_scalar_with_offset
- can_processOne_with_offset

Modify MergedGraph apply_left, apply_right, processOne, and
processOne_simd to not require an offset argument anymore.

Modify all calls to processOne(_simd) to never pass an offset.

Modify TagMonitors processOne to generateTag without offset. The
published tag is now unconditional 0 all the time.

Either the function is const and can work with chunks of inputs, or it
is non-const and cannot work with chunks of input. These functions were
none of these.

With `sink::processOne` being non-const the merged graphs in this
benchmark are always non-SIMD. Consequently the processOne_simd calls
become ill-formed and need to be removed. Thus, there's no difference
anymore when compiling with DISABLE_SIMD and that extra benchmark
executable can go.
