espressif: improve esp-hal-3rdparty handling

Reduce the downloads of esp-hal-3rdparty when using nxtmpdir to store
esp-hal-3rdparty and speedup compilation after `make distclean`.

Usage:
```
~/nuttxspace/nuttx/make distclean
~/nuttxspace/nuttx/./tools/configure.sh -l -S esp32-devkitc:nsh
~/nuttxspace/nuttx/make flash -j 8 ESPTOOL_PORT=/dev/ttyUSB0
~/nuttxspace/nuttx/picocom /dev/ttyUSB0 --baud 115200
```

Result:
```

Any new `make distclean` and configure for a different espressif device
no longer requires the downloading of modules or patching.
