Use correct type name instead of index for TEMPLATE_PRODUCT_TEST_CASE (#1544)

Browse Source 
Previously, for a TEMPLATE_PRODUCT_TEST_CASE("Test" ..., T, (P1, P2)),
the generated test case names were

  Test - 0
  Test - 1

With this commit, the correct typename is used:

  Test - T<P1>
  Test - T<P2>

-----------

MSVC needs another indirection to evaluate INTERNAL_CATCH_STRINGIZE
and also inserts a space before theINTERNAL_CATCH_STRINGIZE_WITHOUT_PARENS
parameter, which we can get rid of by pointer arithmetic.
