Auto-install Frida devkits (#5)

* bump bindgen to 0.57 * automatically download and use the frida devkit This makes the library really usable in other packages * remove the devkit download from the github workflow make sure cd .. happens irrespective of if the download and build line fails * remove static requirement for libfrida-XXX * formatting * Deduplicate build.rs code by creating frida-build; Introduce feature flag 'autodownload' * Add FRIDA_VERSION file * formatting * changed autodownload to auto-download; removed frida-core.h * update FRIDA_VERSION to 14.2.13
