composer 2.4: add api to control vsync period

Add new functions to improve vsync period switching by the platform:
 - Adding a list of supported vsync periods to Config to avoid the need to expose
   separate Configs for each vsync period.
 - Adding an API to set the vsync period with timeline constraints to allow better
   synchronization with vsync period change.
 - Extending onVsync() callback to provide the current vsync period.

Test: rev up composer to 2.4 and test refresh rate switching
