Add Allo to users of MLIR (#225)

> [Allo](https://github.com/cornell-zhang/allo) is a Python-embedded
Accelerator Design Language (ADL) and compiler that
facilitates the construction of large-scale, high-performance hardware
accelerators
in a modular and composable manner. It supports progressive hardware
customizations,
reusable parameterized kernel templates, and composable schedules on top
of MLIR
for productive hardware development.

We gave a talk at the [MLIR Open Design
Meeting](https://mlir.llvm.org/talks/) on 2022-08-11 about our progress,
and the project was finally published in [PLDI
2024](https://dl.acm.org/doi/10.1145/3656401). Since then, Allo has
attracted over 10 industry and academic partners, thanks to its strong
foundation on MLIR.
