Rather check expressions used as patterns directly. Check parentheses by
tagging parenthesized expressions as parenthesized.
This allows us to drop UnexpectedPatternToken and makes it clear why a specific
token is unexpected (because it's invalid in a binding pattern).
This also more uniformly restores messages like "Invalid destructuring
assignment target".

- Remove the InstallFunction variant which just passed its arguments
straight to JSObject::AddProperty
- Change InstallFunction to accept a String rather than a Symbol as all
symbol installation goes through InstallFunctionAtSymbol now. This way
we can avoid the call to Name::ToFunctionName as well
- Add an explicit helper InstallFunctionWithBuiltinId for installing
functions which have a builtin ID. These are always installed with
DONT_ENUM PropertyAttributes so we can remove that parameter, too.
- Remove PropertyAttributes from InstallFunction because it is always
DONT_ENUM.

This changes the split from AssignmentPattern and BindingPattern to Pattern and
BindingPattern. Pattern collects all errors that are invalid in both assignment
and binding pattern contexts. Binding pattern additionally collects errors for
binding pattern contexts (property access isn't a valid target). The
distinction is piggybacked on to distinguish assignment vs binding pattern
errors since binding pattern verification will first throw the binding pattern
error.
Since we don't throw pattern error as binding pattern as well, this can mean
that a later binding pattern syntax error will show up before an early pattern
error. Since that just changes the message to another syntax violation, I think
that's fine.

- Remove an unused param from InstallFunction
- Remove an InstallFunction variant which just rearranges the order of
the arguments
- Consistently use const char* string literals as property names rather
than e.g. factory->return_string() just write "return" because it is
easier for humans to read. All the strings are internalized anyway and
this happens at mksnapshot time, so there is no performance penalty.
- Remove the maybe_prototype arguments to CreateFunction. We always know
at the callsite whether we have a prototype or not, so just call the
variant that takes a prototype or the new CreateFunction variant which
takes a Builtin::name.
- Rename a SimpleInstallFunction variant which was only used for symbols
to InstallFunctionAtSymbol. This also makes it clear that this is the
only case where property_name and function_name differ.
