  [TexMap] Make sure the damage is not propagated at any level when disabled
https://bugs.webkit.org/show_bug.cgi?id=285844

Reviewed by Carlos Garcia Campos.

This change disables damage propagation:
- in the main thread
- in the compositor thread - before the damage is collected
thus improving performance and memory consumption when damage propagation runtime preference is disabled.
