Refactor string matching into util

[devongovett]

Adds two utils to centralize static string matching logic:

• match_str matches both string literals and static template literals
• match_str_or_ident matches a string, static template literal, or an identifier

[height]

Link Height tasks by mentioning a task ID in the pull request title or commit messages, or description and comments with the keyword link (e.g. "Link T-123").

💡Tip: You can also use "Close T-X" to automatically close a task when the pull request is merged.
