Allow installation on longer paths than 90 characters

[georgik]

The installation is limited to 90 characters.
The installer blocks the installation in case of longer path.
It prevents problem with ccache and long path build in libraries like libsodium.

Desired state: user can deploy ESP-IDF to longer paths

Another issue discovered with git:

error: unable to create file examples/bluetooth/bluedroid/ble/ble_throughput/throughput_client/main/example_ble_client_throughput.c: Filename too long

Solution:

git config --system core.longpaths true

This displays another problem when updating submodules:

Cloning into 'C:/projects/tmp/0123456789/0123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789/3/components/bootloader/subproject/components/micro-ecc/micro-ecc'...
fatal: '$GIT_DIR' too big

This seems to affect all modules with longer path.

This seems to be hardwired in the git: aws/aws-iot-device-sdk-cpp-v2#157 (comment)

Alternative installation using ZIP archive also fails on long path:

Running command: cmd.exe /c ""xcopy" /s /e /i /h /q "C:\projects\tmp\AppData\Local\Temp\is-J0AQK.tmp\esp-idf-v4.3.1" "C:\projects\tmp\0123456789\0123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789\b""

WIndows unzip fails in case of extracting to long path even with UNC path
