Support vcpkg integrate bash on Windows

[linquize]

To support vcpkg integrate bash on Windows as well.

based on existing code, modify something

1. For home_path, Get User's directory instead of %HOME%
2. Write .bashrc with '/' style path

bash/sh msys/mingw32(64) or wsl?

msys/mingw
downloads\tools\msys2\msys64 *.ini -->> MSYS2_PATH_TYPE=inherit
env = MSYS2_PATH_TYPE = inherit

test
cmd.exe set MSYS2_PATH_TYPE=inherit && ..\msys2\msys64\usr\bin\ sh.exe -lc "realpath ~"

It doesn't matter you use what bash. When you write something to .bashrc in User's home directory, any bash will read that file.

WSL runs linux version of vcpkg so it is already implemented

Git bash? https://initgeek.com/how-to-use-git-git-bash-and-github/
WSL cross compilation?

@linquize would you mind please clarifying what it is you mean please?
vcpkg already supports invocation via Windows built in command processor (cmd.exe) and also powershell.
bash isn't a native shell on Windows, so I don't know why or how it would be possible to support that officially, unless you could maybe be more specific about a port of bash for Windows which exists that you have tried and is actively maintained.
The only one which springs to mind for me is git bash but I don't use it myself.

[linquize]

Simply append one line to the end of ~/.bashrc, which is C:\Users\user\.bashrc

No need to find where win32 bash is located.

Unrelated to WSL.

Hoping this re-opens the issue.

Reproduction steps:

• start Windows Sandbox
• install Git for Windows ( https://gitforwindows.org/ )
• start a Git for Windows bash instance
• install vcpkg

Observe the following result:

Expected result is that vcpkg notices it is running inside of a bash instance, and does the the integration.
