Add Python-LLDB support for WTF::Vector types.
https://bugs.webkit.org/show_bug.cgi?id=100980
Reviewed by Anders Carlsson.
Add a synthetic child provider for WTF::Vector types.
* lldb/lldb_webkit.py:
(__lldb_init_module): Add both the summary and synthetic providers for WTF::Vector
(WTFVector_SummaryProvider): Wrapper around WTFVectorProvider
(WTFVectorProvider):
(WTFVectorProvider.__init__):
(WTFVectorProvider.num_children): Return m_size+2 children to account for synthesized children.
(WTFVectorProvider.get_child_index): Synthesize child indexes for each entry in the Vector.
(WTFVectorProvider.get_child_at_index): Synthesize children for each entry in the Vector.
(WTFVectorProvider.update): Retrieve state from the underlying Vector.
(WTFVectorProvider.has_children): Vectors always have children.
