Qt: Check field autocomplete for syntactical validity
Currently the autocompletion engine always suggests a protocol
field completion, even in places where it isn't syntactically
valid.
Fix that by compiling the preamble to the token under the cursor
and checking the returned error. If it is DF_ERROR_UNEXPECTED_END
that indicates a field or literal value was expected. Otherwise
a field replacement is not valid in this position.
Fixes #12811.
