#2173: store JetBrains vmoptions under $IDE_HOME/.ide/<ide>/<workspace>

[quando632]

This PR fixes part of #2173 (part of #2142)

Moves the JetBrains VM options out of the workspace into $IDE_HOME/.ide/«ide»/«workspace» for IntelliJ, PyCharm and Android Studio, solved once in their shared superclass.

Stacked on #2175 (#2172 – getIdeMetadataPath()); its commit appears here until #2175 is merged, then rebase onto main.

Scope note (important)

During implementation the .idea folder and the *.properties files turned out to be entangled with the workspace-template-merge mechanism / IntelliJ's project-root convention (and idea.properties is an empty template merged into the workspace relocating only its env var gives no benefit). So this PR intentionally covers only the vmoptions, which are the one metadata written directly by code and thus cleanly relocatable. .idea + *.properties are split out into a dedicated design spike (see follow-up issue) as agreed on #2142.

Implemented changes

• IdeaBasedIdeToolCommandlet.runTool: the .«prefix».vmoptions file is now written to getIdeMetadataPath() instead of the workspace (env var points at the same new path). Covers IntelliJ (.idea.vmoptions), PyCharm (.pycharm.vmoptions) and Android Studio (.studio.vmoptions) via the shared superclass.
• Migration Mig202608002 (target 2026.08.002): backs up the stale .*.vmoptions files from every workspace (they are regenerated at the new location from the «IDE»_VM_ARGS variable on next launch). Registered in IdeMigrator.
• Updated IntellijTest, PycharmTest, AndroidStudioTest to assert the new location; added Mig202608002Test.

Testing instructions

1. cd cli && mvn -Dtest=IntellijTest,PycharmTest,AndroidStudioTest,Mig202608002Test,IdeMigratorTest test all pass.
2. Manual: set INTELLIJ_VM_ARGS in your project, run ide intellij, verify .idea.vmoptions is created under $IDE_HOME/.ide/intellij/«workspace»/ and not in the workspace.
