[browser] Trigger relink on `EmccMaximumHeapSize` change

[ilonatommy]

Expectations:

• EmccMaxHeapSize is set -> relink
• If there's no workload -> fail

Use WBT added in #104662.

Shouldn't we think more broadly? We have plenty of properties and items that modify native build and that don't trigger it.

Should we go through whole

runtime/src/mono/wasm/build/WasmApp.Common.targets

Line 6 in 8602bb3

Public properties (optional):

list and see which ones should relink and add them to props json? Or did you have different approach in mind?

Probably I guess. It's of a thing to think about. Also, items are involved as well.

• Do we want to always set WasmNativeBuild on behalf of the user?
• Do we want to do it only for high frequently used props & items?
• Do we want to do it for random props & items? 🙃
• If we don't do it for everything, we should document the behavior.
