Don't run Gzip and Brotli compressors in development

[mischnic]

Allow returning null or undefined from compressors to skip that plugin based on some condition at runtime, and use that to only run the gzip and brotli compressors in production. This is technically a breaking change but I can't image you would want the old behaviour

Other small fixes:

• add compressor to TS types, closes Compressor type is not in .d.ts file for @parcel/plugin #7507
• add a few more md escapes for error messages, closes Slashes and backslashes missing in "file doesn't exist" message #7509

[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.

Looks like some failing tests?

[devongovett]

Unit tests are still failing on Windows. Maybe something to do with the markdown escaping?
