linker scripts: Add explicit symbols for _iram_start and _flash_cache_start

This is to avoid confusion when idf_monitor prints the first symbol in each section, ie "WindowOverflow4" or similar,
when bootloader prints the section mapping address.

Closes #447 https://github.com/espressif/esp-idf/issues/447
