Remove most usages of npx

[jsnajdr]

Inspired by some changes in #62003 that @noahtallen did, this PR removes most usages of npx from Calypso scripts, and replaces them with some form of yarn run or yarn run -T.

The rules I'm following are:

• if the package that provides the binary is a direct dependency of a package, the binary can be invoked with yarn run, no matter in which node_modules/.bin directory it actually lives after hoisting. Yarn will find it.
• if the package that provides the binary is a dependency of the root package.json, then we can invoke it with yarn run -T.

The apps/happychat and apps/inline-help builds are failing with:

Usage Error: Couldn't find a script name "rimraf" in the top-level (used by @automattic/inline-help@workspace:apps/inline-help).

which is strange because rimraf is declared and installed in the top-level package.json.

Oh that's interesting. I think that could be because the TeamCity build for these apps uses yarn workspace focus to avoid having to yarn install the entire repo. It seems very plausible that focusing on a single workspace won't link any dependencies (and therefore bin scripts) from the top-level node_modules.

I'm guessing we can fix it by adding rimraf as a dev dependency locally. IIRC this is what scinos had been doing in a lot of cases: just explicitly adding every single dependency in every package which needed it after running yarn workspace focus
