build: use m1 hosts to build apple silicon binaries (#38258)

* build: try m1 speed test

* yolo?

* build: fix gn binary on m1

* build: remove arm64 snapshot logic

* build: strip x64 on arm64 hosts...

* if is fi

* build: no more GENERATE_CROSS_ARCH_SNAPSHOT

* build: chromedriver inline on arm64 darwin

* build: no copy chromedriver

* build: use m1 for publish

* medium?
