Merge string concatenation
Merge string and template literal concatenation into a single template literal or string.

Template literals are string templates that can include variables and expressions.
They can replace string concatenation and are often easier to read. Example: `Hello, ${name}!`
Mechanics
This refactoring supports converting the first line of concatenated strings into template literals or shortened strings:
- concatenated string literals will be combined, e.g.
"a" + "b"
will become"ab"
- concatenated expressions and variables will be embedded in templates, e.g.
"a" + x + "b"
will become`a${x}b`
- unnecesary escaping of quotes is removed when string are combined or transformed into template literals
