[Reporting] Switch Mac Chromium to the internally-hosted custom build

[tsullivan]

Summary

As of #98688, the Reporting team has decided to no longer bundle custom builds of Chromium's headless_shell for Mac and Windows. This presented an unforeseen change for the Mac release cycle. Infra team signs and notarizes the Kibana build for Mac, to comply with Apple Gatekeeper requirements. Our signing scripts did not know how to handle Chromium.app bundled with Kibana.

This PR switches Mac to bundle a custom headless_shell binary for Mac, which is built to be compatible with Puppeteer 8.0.0.

but never appeared in a declare_args() block in any buildfile.

To view all possible args, run "gn args --list <out_dir>"

The build continued as if that argument was unspecified.

Note about vim chromium/src/headless/BUILD.gn -- I had to edit this file to find a workaround for https://groups.google.com/a/chromium.org/g/chromium-dev/c/jYibDVPm5X0/m/lQ1yBL0wBAAJ

How to test on Mac

Testing can be automated with the functional tests:

node scripts/functional_tests.js --config x-pack/test/reporting_api_integration/reporting_and_security.config.ts --grep='PDF'
node scripts/functional_tests.js --config x-pack/test/functional/config.js --grep='downloads a PNG'
