Resolve the pinned ESP-IDF version and cache the native ESP-IDF install
(toolchains + source) at ~/.esphome-idf. Every job that installs ESP-IDF
natively (clang-tidy for IDF/Arduino and the component test batches) shares
one cache, since the install is identical (ESPHOME_IDF_DEFAULT_TARGETS
defaults to "all", so all toolchains are present regardless of the chip).
one cache, since the install is identical: ESPHOME_IDF_DEFAULT_TARGETS
defaults to "all", and _get_configured_targets() in espidf/toolchain.py
skips per-variant narrowing whenever CI is set, so all toolchains are
present regardless of the chip a job builds.
Callers must set env ESPHOME_ESP_IDF_PREFIX: ~/.esphome-idf and have the
Python venv already restored.
