[PATCH v2 0/2] MR6760: msi: Make MsiInstallProductW open msi readonly

[Fabian Maurer (＠DarkShadow44)]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=57343

This is what the Java JRE installer does:

- It calls MsiInstallProductW - this opens the msi read/write
- The msi runs installer.exe
- installer.exe tries to open the msi readonly

  v2: msi: Make MsiInstallProductW open msi readonly
      msi/tests: Add test for MsiOpenDatabaseA during MsiInstallProductA
