feat(profiling) add stream_select()-type functions to timeline

[realFlowControl]

Description

This will wrap functions that are used to wait on blocking I/O, like stream_select() and others. It also moves the frankenphp_handle_request() to the idle visualisation because technically it is waiting on I/O, but it is used to wait for the next request, just like RSHUTDOWN -> RINIT so it should share the same vis.

In async PHP (using ReactPHP, AMPHP or others), spending time in a stream_select()-type function call means the event-loop is idle.
