Add ResNet benchmark

[laggui]

Related Issues/PRs

Closes #1521

Changes

Added ResNet-50 inference in backend-comparison

• New build script to fetch the resnet-burn implementation and apply a diff patch to be compatible with the current version of Burn on main
• ResNetBenchmark executes a forward pass on a random input w/ shape [1, 3, 224, 224]
• Two minor typos fixed

Note: doesn't include autodiff but could be added if required, similar to the current gelu benchmark

Testing

Ran the benchmark with multiple backends

cargo run --release --bin burnbench -- run --benches resnet50 --backends tch-gpu tch-cpu wgpu wgpu-fusion ndarray

Note: it doesn't run on candle because AdaptiveAvgPool2d in the model uses padding which is not supported.

Hmm CI failed but the failing test is unrelated to this PR

/edit: looking for feedback on the benchmark implementation but let's wait until we optimize some stuff before we actually merge it.

This will simply be a helpful tool to evaluate the improvements along the way and once we're satisfied with the results we can merge.

LGTM so far, great work!
