[eslint-config] eslint-bulk-suppressions causes excessive file system calls

[dmichon-msft]

Summary

Enabling the eslint-bulk-suppressions patch slows down eslint substantially by introducing many file system accesses during linter execution. Lint rule execution should ideally not touch the file system once the source file has been read.

Repro steps

Enable the eslint-bulk-suppressions patch, run linting.

Expected result:
Exactly one file system access from the feature, to read the .eslint-bulk-suppressions.json file from a known computed path.

Actual result:
For every unique directory containing a file being linted, the eslint-bulk-suppressions patch probes the file system looking for .eslintrc.cjs or .eslintrc.js files.

Details

Considering that the eslint-bulk-suppressions patch is applied by invoking it from the project's .eslintrc.js file, it should be trivial to either pass in __filename to a function returned from the patch object, or else read the path to the .eslintrc.js file from the NodeJS require stack.
