  -----------
  [mlir][emitc] Add a common type converter (#203763)

MemRef type conversion is currently implemented as part of the memref
dialect lowering pass, which means e.g. that func-to-emitc cannot lower
functions taking MemRef types as arguments.

This patch refactors the existing type conversions in EmitC's lowering
passes into a structure similar to the LLVM dialect by adding a common
EmitC type converter and using it across dialect-specfic EmitC lowering
passes and the generic convert-to-emitc pass.
