MdeModulePkg/AcpiTableDxe: consider version mask when removing tables
Invocations of EFI_ACPI_TABLE_PROTOCOL::UninstallAcpiTable() may result in a crash when the value of PcdAcpiExposedTableVersions does not include EFI_ACPI_TABLE_VERSION_1_0B. The reason is that EFI_ACPI_TABLE_PROTOCOL::InstallAcpiTable() will only populate the Rsdt1/Rsdt3 pointers when EFI_ACPI_TABLE_VERSION_1_0B is set, whereas EFI_ACPI_TABLE_PROTOCOL::UninstallAcpiTable() will invoke PublishTables with EFI_ACPI_TABLE_VERSION_1_0B alawys set, resulting in a NULL pointer dereference of the Rsdt1/Rsdt3 pointers. So take PcdAcpiExposedTableVersions into account for UninstallAcpiTable as well.
