Testing of Ivy revealed two bugs in the AstMemoryEfficientTransformer
class, a part of existing View Engine compiler infrastructure that's
reused in Ivy. These bugs cause AST expressions not to be transformed
under certain circumstances.
The fix is simple, and tests are added to ensure the specific expression
forms that trigger the issue compile properly under Ivy.

When template bindings are being parsed the event handlers
were receiving a source span that included the whole attribute.
Now they get a span that is focussed on the handler itself.
PR Close#28055
Previously, it wasn't possible to compile template that contains pipe in context of ternary operator `{{ 1 ? 2 : 0 | myPipe }}` due to the error `Error: Illegal state: Pipes should have been converted into functions. Pipe: async`.
This PR fixes a typo in expression parser so that pipes are correctly converted into functions.

A long time ago Angular used to support both those attribute notations:
- `*attr='binding'`
- `template=`attr: binding`
Because the last notation has been dropped we can refactor the binding parsing.
Source maps will benefit from that as no `attr:` prefix is added artificialy any
more.
PR Close#23460
Template expressions can now use a post-fix `!` operator
that asserts the target of the operator is not null. This is
similar to the TypeScript non-null assert operator. Expressions
generated in factories will be generated with the non-null assert
operator.
Closes: #10855
