Subject: [PATCH] PackageToJS: Rename SWIFT_PATH to SWIFT_BIN_PATH env var

Utilities/format.swift now looks up `SWIFT_PATH` for the "swift"
command location, but PackageToJS's test suites also use this env var
to locate the Swift toolchain bin path. To avoid confusion, rename
the env var in PackageToJS from `SWIFT_PATH` to `SWIFT_BIN_PATH`.
