[9.x] Improve Blade compilation exception messages

[danilopinotti]

Problem

Currently, when we write a @foreach or @forelse the wrong way, the exception message is not descriptive. e.g:

Code:

@foreach
TEST
@endforeach

Exception:

The main objective of this PR is to improve this message:

In an actual situation, it occurred for a beginner developer to take hours to discover the problem since the stacktrace also doesn't make it easy to debug issues in rendering views.

Because the regex quantifier after "as" was changed from * to +, if the foreach statement is multiline, this now throws an error:

@foreach ($foo as
$bar)

Should this be considered?
