lcd/lcm1602/jhd1313m1: remove lcm1602 and jhd1313m1 from lcd library

The lcm1602 and jhd1313m1 drivers had been rewritten in C with a C++
wrapper some time ago, however the original lcm and jhd drivers were
still present in the lcd library.  In addition, to avoid header file
conflicts, the new, separated lcm and jhd header files were renamed
with a .hxx prefix.

This patch:

- renames the new lcm1602/ and jhd1313m1/ header files to have the
  usual .hpp prefix.

- removes the lcm1602, jhd1313m1, and sainsmartks drivers from the
  lcd/ (i2clcd) library.

- fixes the examples to use the "new" libraries (lcm1602 and
  jhd1313m1)

- changes the argument type for the createChar() (C++) to use a byte
  vector (std::vector<uint8_t>) rather than a typedef'd char array.
  The lcm1602_create_char() function (C) uses a standard char *.  The
  use of std::vector is well supported by SWIG.

- SWIG interface files changed to use upm_vectortypes.i, and removes
  the carrays helpers, which should no longer be needed for these
  drivers.

- removes the inclusion of the driver C .h header files into the SWIG
  interface files - this should not be needed for these drivers.

- the sainsmartks driver will be placed into it's own new lcdks (LCD
  Keypad Shield) library.  This library should support the
  SainsmartKS, DFRobot LCD Keypad Shield, and similar products from
  other manufacturers in a future commit.
