Automerge: [mlir][spirv] Fix incorrect argument erasure in deserializer (#134610)

The current implementation iterates and modifies the list of arguments
at the same time. Depending on the number of arguments this will trigger
an assert: `assert(index < arguments.size())`. This change replaces loop
with a range based erasure.
