* Introduce reusable QL plugin for SQL and EQL (#50815)
Extract reusable functionality from SQL into its own dedicated project QL.
Implemented as a plugin, it provides common components across SQL and the upcoming EQL.
While this commit is fairly large, for the most part it's just a big file move from sql package to the newly introduced ql.

Break DataType enums into QL (default) and SQL types
Make data type conversion pluggable so that new types can be introduced
As part of the process:
- static type conversion in QL package (such as Literal) has been
removed
- several utility classes have been broken into base (QL) and extended
(SQL) parts based on type awareness
- operators (+,-,/,*) are
- due to extensibility, serialization of arithmetic operation has been
slightly changed and pushed down to the operator executor itself
