[mlir][tosa] Change the type of profile option to ListOption (#111214)
In tosa valiation pass, change the type of profile option to ListOption.
Now TOSA profiles is turned from hierarchical to composable. Each
profile is an independent set, i.e. an target can implement multiple
profiles.
Set the profile option to none by default, and limit to profiles if
requested.
The profiles can be specified via command line, e.g.
$ mlir-opt ... --tosa-validate="profile=bi,mi" which tells the valiation
pass that BI and MI are enabled.
