[Composer] Fix compiler warnings
When included by SurfaceFlinger, there were various warnings in the
ComposerCommandBuffer headers for conversions with -Wconversion enabled
that necessitated disabling that warning for these headers. These have
been fixed by adding explicit static_casts to the needed integer type.
In addition "#warn" was not a valid preprocessor directive, as used at
the top of each file if LOG_TAG is not defined. This was replaced by a
correct "#warning" directive.
Finally, there were also some unused includes reported by in-editor
clangd checks. Those have been removed.
Flag: EXEMPT build and lint warnings only
