compiler: Support animations on global properties in LLR

[ImFeH2]

Before, remove_aliases move animation from an alias property to the global property it aliases. The interpreter already handled that, but the LLR/codegen path still assumed that global properties don't have animations, which caused a panic.

This keeps the animation on the lowered GlobalComponent and expose it through property_info(), so generated setters can still use set_animated_value(). The remove_unused pass and pretty_printer now handle the animation map as well.

Fixes: #9961

The repro case compiled as a Rust app now matches the viewer behavior: the global property update animates instead of panicking.
