* [pin_remap 1/3] platform: define ARDUINO_CORE_BUILD when building core files
* [pin_remap 2/3] core,libs: add pin remap hooks
* platform: remove previous build options if file is missing
"touch" would create the file if not present, but not delete its
contents if a previous run left the file in the build dir.
* platform: make debug_custom.json file customizable by board
* platform: fix default debug prefix
"debug.toolchain.prefix" must end with a dash, since only the tool name is
appended to this string.
The reason this is not a major issue is that the "debug_custom.json" file
(copied in the sketch directory when debugging is enabled) forces its own
prefix. And to make things more interesting, the "toolchainPrefix" entry
in that file should _not_ end with a dash.
* [pin_remap 3/3]: add Arduino Nano ESP32 board
* fix: periman: include it by default, add include guard
* fix: io_pin_remap: adjust for new perimap APIs
* fix: libraries: manually handled pin remapping files
Previously all libraries invoked either high-level APIs (transparently
remapped, like the user sketch) or low-level ESP-IDF calls (where the
remap to GPIO numbers had to be added manually).
Since 3.x, some of these are mixed (for example, periman* APIs are
remapped, while soc* are not). This must be handled by disabling the
automatic API remapping and making sure all calls use GPIO numbers.
* feat: show remapped pins in chip debug reports
