Tests show that IsThemePartDefined() doesn't use state ID to search parts. If a part of any state is
present, the part is considered as defined. For example, disabled state of part EditText of class
Edit is present in theme files but there is no default state for part EditText. So
IsThemePartDefined(theme, EP_EDITTEXT, 0) failed previously and it should succeed.

Currently there is no need to hook DefDlgProc(). Tests show that dialog theming shouldn't be
implemented in DefDlgProc().
Also fix a double free bug because WM_DESTROY in UXTHEME_DefDlgProc() calls CloseThemeData() even
when the theme handle is not opened when handling WM_CREATE in UXTHEME_DefDlgProc(). The bug can
be demonstrated by running comctl32/tests/propsheet.c tests with Light theme.

When a theme is already active and a user tries to activate another theme,
the new theme configuration should be written to the registry so that it's
still in effect after a wine reboot.

Only save unthemed system metrics to the registry when the LoadedBefore
registry key value is '0'. This avoids saving themed system metrics
when two processes are trying to activate theming at the same time.

So that temporary system metrics are not saved in the registry. Saving
them to the registry creates a race condition when two processes are
trying to activate theming at the same time, one process might save
themed system metrics instead of unthemed system metrics to the registry.
The race condition will be more apparent when initializing a wine prefix
after theming is turned on by default in wine.inf.
This patch refactors the system metric helper functions to use an
in-memory struct and is a prerequisite to remove the race condition.

Fix a bug that font size may be smaller than normal after toggling theming.
For example, the following steps will change the system metrics to incorrect values.
1. Open winecfg, and set DPI to 192. Do not restart winecfg.
2. Change the theme to Light. UXTHEME_BackupSystemMetrics() backs up system metrics in 96 DPI
because the current DPI is still 96.
3. Restart winecfg and turn off theming. UXTHEME_RestoreSystemMetrics() restores system metrics in
192 DPI because the current DPI is 192. So system metrics will be scaled to 1/2 of the original size.
