[MWRAPPER-122] Mingw paths problem on Windows

Start with the mvnw script and its existing Cygwin path-conversion branch. Reproduce the Taskfile.dev invocation in Windows Git Bash, then verify that the generated Java command uses compatible path separators for the classpath and project directory. Done means the Maven wrapper runs clean install -N without the ClassNotFoundException.

When I call the Maven wrapper from Taskfile.dev then only on Windows in GitBash (on Mac and Linux works without problems) the following command is executed (I just replaced the last "exec" statement with "echo" to troubleshoot):

/c/Program Files/Eclipse Adoptium/jdk-11.0.14.101-hotspot/bin/java -classpath C:\Projects\acme-aem-acme-mono-ad86003b367a/.mvn/wrapper/maven-wrapper.jar -Dmaven.multiModuleProjectDirectory=C:\Projects\acme-aem-acme-mono-ad86003b367a org.apache.maven.wrapper.MavenWrapperMain clean install -N

Note that bad path separators are generated and my task execution results in an error:

task: [aem:build:root] sh mvnw clean install -N && mkdir -p target && touch target/done.txt
Error: Could not find or load main class org.apache.maven.wrapper.MavenWrapperMain
Caused by: java.lang.ClassNotFoundException: org.apache.maven.wrapper.MavenWrapperMain
task: Failed to run task "aem:build:root": exit status 1

To fix the problem I needed to update the code:

1. For Cygwin, switch paths to Windows format before running java
if $cygwin; then

to the following:

1. For Cygwin or Mingw, switch paths to Windows format before running java 
if [ "$cygwin" = true ] || [ "$mingw" = true ]; then

then I have a working exec command generated:

/c/Program Files/Eclipse Adoptium/jdk-11.0.14.101-hotspot/bin/java -classpath /c/Projects/acme-aem-acme-mono-ad86003b367a/.mvn/wrapper/maven-wrapper.jar -Dmaven.multiModuleProjectDirectory=/c/Projects/acme-aem-acme-mono-ad86003b367a org.apache.maven.wrapper.MavenWrapperMain clean install -N

It would be nice to make the "mvnw script work in more use cases. by introducing the fix like the above or similar making my integration work without problems.
