Extend theme converter to allow multimatching against vscode colors (#3294)
[[PR Description]]
Adds the ability to specify a vec of VScode syntax scopes to match
against for a given syntax style.
Example:
```rust
pub fn to_vscode(&self) -> Vec<&'static str> {
use ZedSyntaxToken::*;
match self {
SyntaxAttribute => vec!["entity.other.attribute-name"],
SyntaxBoolean => vec!["constant.language"],
SyntaxComment => vec!["comment"],
SyntaxCommentDoc => vec!["comment.block.documentation"],
SyntaxConstant => vec!["constant.character"],
SyntaxConstructor => vec!["entity.name.function.definition.special.constructor"],
SyntaxEmbedded => vec!["meta.embedded"],
SyntaxEmphasis => vec!["markup.italic"],
SyntaxEmphasisStrong => vec![
"markup.bold",
"markup.italic markup.bold",
"markup.bold markup.italic",
],
SyntaxEnum => vec!["support.type.enum"],
SyntaxFunction => vec![
"entity.name.function",
"variable.function",
"support.function",
],
SyntaxKeyword => vec!["keyword"],
SyntaxLabel => vec![
"label",
"entity.name",
"entity.name.import",
"entity.name.package",
],
// .. more styles
}}
```
