Fixes #8069

GCC 10.3 has a patch to stop escaping the initial : in Windows paths which
is causing Arduino and other tools to fail dependency checks and rebuild
everything on every compile.

#8069 is fixed with this PR.
I only tried the windows version through the alpha release installer which includes this PR.
First compilation of FSBrowser.ino took 2m12s. Second one took 27s.

@d-a-v I installed the board from the link
version 0.0.2: git: 3.0.0-97-g11e1175c https://d-a-v.github.io/esp8266/Arduino/package_esp8266com_index.json
After installation I see gcc 10.2
C:\Users\Alex1\AppData\Local\Arduino15\packages\esp8266\tools\xtensa-lx106-elf-gcc\3.0.0-newlib4.0.0-gnu23-48f7b08\xtensa-lx106-elf\include\c++\10.2.0\
Сompilation time does not change

@sh-user
You should see gcc-10.3
Snapshot and alpha release are not officially supported by arduino and I sometimes see the same issue as you see, or some other times a java.nullpointer.exception.
In this case, what works is to remove esp8266\ in C:\Users\name\AppData\Local\Arduino15\Packages\ before installing 0.0.1 or 0.0.2 again.
BTW, a new updated gcc-10.3 version has just landed in alpha release v0.0.2 that I'm about to try with windows.

edit: the new gcc10.3 works (long first compilation, short second compilation, flash& run OK from windows)
edit2: it is now in the snapshot release too (0.0.1)

I deleted the folder C:\Users\Alex1\AppData\Local\Arduino15\ and reinstalled the Arduino IDE 1.8.13 again

According to your logs @sh-user you installed the version 3.0.0, not 0.0.2 nor 0.0.1
(3.0.0-newlib4.0.0-gnu23-48f7b08 should be 3.0.3-gcc10.3-9bcba0b)

@d-a-v sorry, this is my mistake, installed version 3.0.0 instead of 0.0.2, everything works, second compilation 50 seconds!

Don't forget @sh-user that versions 0.0.1 and 0.0.2 can only receive manual updates.
No notification will come through the arduino IDE for 0.0.1 & 0.0.2, nor the official release channel for 3.0.1 when it is out.
