[BUG] Windows build broken

[dblock]

Describe the bug

Trying to build on Windows fails in multiple ways.

1. `Unable to allocate an initial java heap of ...`

Workaround: export _JAVA_OPTIONS: -Xmx4096M

Install 64-bit Java from https://adoptium.net/releases.html?variant=openjdk11.

2. Could not determine the dependencies of task ':qa:full-cluster-restart:v1.2.0#upgradedClusterTest'.

* What went wrong:
Could not determine the dependencies of task ':qa:full-cluster-restart:v1.2.0#upgradedClusterTest'.
> Could not resolve all task dependencies for configuration ':qa:full-cluster-restart:opensearch_distro_extracted_testclusters-qa-full-cluster-restart-v1.2.0-1-1.2.0-'.
   > Could not resolve project :distribution:bwc:minor.
     Required by:
         project :qa:full-cluster-restart
      > Project :qa:full-cluster-restart declares a dependency from configuration 'opensearch_distro_extracted_testclusters-qa-full-cluster-restart-v1.2.0-1-1.2.0-' to configuration 'expanded-windows-zip' which is not declared in the descriptor for project :distribution:bwc:minor.

and related tests

InternalDistributionBwcSetupPluginFuncTest. builds distribution from branches via archives assemble
InternalDistributionBwcSetupPluginFuncTest. bwc distribution archives can be resolved as bwc project artifact
InternalDistributionBwcSetupPluginFuncTest. bwc expanded distribution folder can be resolved as bwc project artifact

3. Docker (checked [/usr/bin/docker, /usr/local/bin/docker]) is required

* What went wrong:
Docker (checked [/usr/bin/docker, /usr/local/bin/docker]) is required to run the following tasks:
:distribution:docker:buildArm64DockerImage
:distribution:docker:buildDockerImage

Symlink of /c/Program Files/... to /user/bin/docker didn't work.

4.:distribution:docker:buildDockerImage

Execution failed for task ':distribution:docker:buildDockerImage'.
> A failure occurred while executing org.opensearch.gradle.docker.DockerBuildTask$DockerBuildAction
   > Failed to pull Docker base image [centos:8], all attempts failed

^ fixed in #1412

5. ./gradlew :test:fixtures:azure-fixture:composeUp

6. ./gradlew assemble tries to assemble docker images for CentOS

To Reproduce

Run ./gradlew build on Windows.

We have a docker problem on my machine (works on @reta's machine with Docker 3.6) in #1425, and a cross-platform build issue in #1430. Otherwise windows build works A-OK after #1412, so I am going to close this.

We do need CI for Windows. Let's take it up part of opensearch-project/opensearch-build#33
