LOG: [NFC][mlir][tosa] Use optnone for compliance initialization under ASan (#229292)

Similar to #223586 and #226310, compiling the ~5,000-line generated
initializer in `TosaProfileCompliance::TosaProfileCompliance()` is also
very slow under AddressSanitizer.

Mark the constructor with `optnone` under `LLVM_ADDRESS_SANITIZER_BUILD`
as well to skip expensive optimization and register allocation passes.
