Subject: [PATCH] Add riscv64 build support (#7309)

Lighthouse does not compile on the _riscv64_ architecture due to a missing target configuration in the `bls_hardware_acceleration` function.


  Added support for compiling Lighthouse on the riscv64 architecture by explicitly handling the _riscv64_ target in the bls_hardware_acceleration function.
Specifically, this line was added:
```
#[cfg(target_arch = "riscv64")]
return false;
```
This prevents a compilation error on RISC-V.
