internal: few more marginal optimisations from profiling (#8271)

* deco: reduce local temporars and function calls

profiling shows this is a high used function, reduce the amount of
function calls and local temporar copies and also check if we even need
to add extents at all in the loop.

* popup: optimize bfhelper in popups

pass nodes as const reference and reserve the size of the children node
vector help reduce the reallocations.

* procotol: make compositor bfhelper use const ref

use const ref for nodes and reserve second nodes vector size to reduce
amount of reallocation needed.
