Make clean scripts platform independent

[Anders-E]

Currently, a lot of the cleaning scripts in many of the package.json do not work on Windows due to them running the rm command. This would work in PowerShell but not in cmd which is what Node seems to use to run scripts defined in package.json.

As an example, this leads to these errors when running the initial yarn run bootstrap:

Before

expo-codemod: $ yarn run clean && yarn build
@expo/json-file: $ yarn run clean && yarn build
@expo/osascript: $ yarn run clean && yarn build

@expo/schemer: $ yarn build
expo-codemod: $ rm -rf build ./tsconfig.tsbuildinfo
@expo/json-file: $ rm -rf build ./tsconfig.tsbuildinfo
@expo/osascript: $ rm -rf build ./tsconfig.tsbuildinfo
@expo/image-utils: $ rm -rf build ./tsconfig.tsbuildinfo

Notice all the 'rm' is not recognized as an internal or external command lines leading to the commands returning error code 1.

I suggest using the rimraf package for these cleanups to render them platform independent.

With this change we get no errors when we run the clean scripts:

After

@expo/image-utils: $ yarn run clean && yarn build
expo-codemod: $ yarn run clean && yarn build
@expo/json-file: $ yarn run clean && yarn build
@expo/osascript: $ yarn run clean && yarn build
@expo/package-manager: $ yarn run clean && yarn build
@expo/plist: $ yarn build
@expo/schemer: $ yarn build
expo-codemod: $ rimraf build ./tsconfig.tsbuildinfo
@expo/image-utils: $ rimraf build ./tsconfig.tsbuildinfo
@expo/json-file: $ rimraf build ./tsconfig.tsbuildinfo
@expo/plist: $ tsc
