Andi Drebes 6fb907295d feat(compiler): Add lowering for HLFHELinalg.zero to linalg.generate ...

Add a rewrite pattern that transforms an instance of
`HLFHELinalg.zero` into an instance of `linalg.generate` with an
appropriate region yielding a zero value.

Example:

  %out = "HLFHELinalg.zero"() : () -> tensor<MxNx!HLFHE.eint<p>>

becomes:

  %0 = tensor.generate   {
    ^bb0(%arg2: index, %arg3: index):
       %zero = "HLFHE.zero"() : () -> !HLFHE.eint<p>
       tensor.yield %zero : !HLFHE.eint<p>
  } : tensor<MxNx!HLFHE.eint<p>>
