[lldb] Add lookup by name to SBValue through new member property (#118814)

Browse Source 
Introduces a `member` property to `SBValue`. This property provides pythonic access to a
value's members, by name. The expression `value.member["name"]` will be an alternate
form form of writing `value.GetChildMemberWithName("name")`.
