🏗 Rewrite gulp lint using the nodejs API of eslint

[rsimha]

This is the first in a series of PRs that modernize our development tasks.

PR Highlights:

• Directly use the eslint nodejs API
• Eliminate file streaming via gulp.src
• Remove dependencies gulp-eslint, gulp-eslint-if-fixed, gulp-debounce, and lazypipe
• Remove --watch and --quiet (on-the-fly IDE linting has made them obsolete)

Notes:

• I'm sure it's possible to parallelize this task (we'll likely have to eliminate live logging). I'm leaving that for a follow up PR.
