Optimizer rules should work with qualified column names

[alamb]

Note: migrated from original JIRA: https://issues.apache.org/jira/browse/ARROW-10894

We have a number of optimization rules that deal with column names represented by strings.

In order to support qualified field names in queries we need to update these rules to work with a data structure representing optionally qualified column names instead.

Suggested data structure:
{code:java}
struct ColumnName {
qualifier: Option,
name: String
} {code}
