This is the second step towards moving away from sending `url` with
every call frame when emitting the `Debugger.paused` event.

The previous implementation would not explicitly send
`Debugger.paused` events for instrumentation breakpoints
if they were to overlap with breaks due to:
* regular breakpoints
* OOM
* exceptions
* asserts
This CL is a step towards making sure that a separate
`Debugger.paused` event is always sent for an instrumentation
breakpoint. In some cases where we have overlapping reasons
but only know of one, the 'instrumentation' reason,
we still just send out one paused event with the reason
being `instrumentation`.
Drive-by: send instrumentation notification to all sessions,
remember which breakpoints are instrumentation breakpoints

These tests unnecessarily rely on the `//# sourceURL` annotation. This
is preparatory work to eventually move the treatment of `sourceURL` to
the DevTools front-end.

Add a test for a module without a start function; in that case, we want
to break when first calling into the module (via an exported function).

This CL adds support for instrumentation breakpoints in wasm. The
request for "break on entry" is set on the script, and we need to keep
it stored there because there might not be any instances of that wasm
module yet. Once instances get created, the flag value is transferred to
all instances. The flag stored there is then checked in the function
prologue in Liftoff debugging code. This ensures that we will stop at
the first valid break position in any function within that module.
Hitting that instrumentation breakpoint will then clear the flag from
the script and from all other live instances (in the same isolate).
A first basic test is contained in this CL. More tests will be added
later.
