Unrolled build for rust-lang#131170

Rollup merge of rust-lang#131170 - madsmtm:target-info-esp32-vendor, r=workingjubilee

Fix `target_vendor` in non-IDF Xtensa ESP32 targets

`rustc`'s Xtensa ESP32 targets are the following:
- `xtensa-esp32-none-elf`
- `xtensa-esp32-espidf`
- `xtensa-esp32s2-none-elf`
- `xtensa-esp32s2-espidf`
- `xtensa-esp32s3-none-elf`
- `xtensa-esp32s3-espidf`

The ESP-IDF targets already set `target_vendor="espressif"`, however, the ESP32 is, from my understanding, produced by Espressif regardless of whether using the IDF or not, so we should set the target vendor there as well?
