Remove legacy esp8266 toolchain support (#2794)

This PR removes legacy toolchain cruft from the framework. - Old esp8266 libc support not required. All esp-quick-toolchain compiler versions use newlib. - Change compiler version check to error. Code won't work with old toolchains. - Remove use of GCC_VERSION_COMPATIBLE from UPnP library. Framework does check, libraries don't need to.
