When Ew.dEe or Gw.dEe output has an exponent requiring more than 'e'
digits, the whole output field must overflow to asterisks. The runtime
was detecting short fields and padding them with zeroes, but not
overflow.

Implements UTF-8 encoding and decoding for external units
with OPEN(ENCODING='UTF-8'). This encoding applies to default
CHARACTER values that are not 7-bit ASCII as well as to
the wide CHARACTER kinds 2 and 4. Basic testing is in place
via direct calls to the runtime I/O APIs, but serious checkout
awaits lowering support of the wide CHARACTER kinds.

When an Fw.d output edit descriptor has a "d" value exactly
equal to the number of zeroes after the decimal point for a value
(e.g., 0.07 with F5.1), the Fw.d output editing code needs to
do the rounding itself to either 0.0 or 0.1 after performing
a conversion without rounding (to avoid 0.04999 rounding up twice).

B/O/Z integer output editing must not reflect any sign extension
of scalar output values. Add more size-dependent OutputInteger
I/O APIs and kind instantiations of EditIntegerOutput.

MSVC does not support a distinct 80-bit extended precision
"long double" type. Rework the I/O runtime to avoid using
native C/C++ type names. Centralize the mappings between
the KIND= type parameters of REAL and their binary precisions
in the common real.h header file, and use KIND type parameter
values rather than binary precisions for clarity where
appropriate.
This patch, if successful, should obviate the need for
Differential review D88511.
(This patch anticipates a successful review of D88688, which
fixes the function that maps each kind of real to its maximum
number of significant decimal digits.)

Fix F output editing in the Fortran runtime so that it
respects the 'd' count of digits after the decimal mark.
