Add a debug bounds-check to absl::string_view::operator[]

string_view accesses that are out-of-bounds are undefined behavior:
https://en.cppreference.com/w/cpp/string/basic_string_view/operator_at

This change causes code to abort in debug mode, indicating a bug and
possibly a security issue like a buffer overflow. Code broken by this
change should be investigated.

Add debug assertions to absl::string_view::front and absl::string_view::back

Calling front() or back() on an empty string_view is undefined behavior. This
assertion is to help catch broken code.

https://en.cppreference.com/w/cpp/string/basic_string_view/back
