[flang][runtime] Prepare enabling PRINT of integer32 for device. (#86247)

This commit adds required files into the offload build closure,
which means adding RT_API_ATTRS and other markers.

The implementation does not work for CUDA yet, because of
std::variant,swap,reverse usage. These issues will be resolved
separately (e.g. by using libcudacxx header files).

[flang][runtime] Handle unconsumed repeated list-directed input items (#75400)

[flang][runtime] Handle unconsumed repeated list-directed input items (#75400)

If list-directed input contains a repeated item ("20*123.0") that is not
fully consumed by the READ statement's data item list, the end of that
READ statement was repositioning the input to the repeated value
("123.0"), leading to later confusion. Cancel the input item repetition
during EndIoStatement() processing to prevent this misbehavior.

Fixes llvm-test-suite/Fortran/gfortran/regression/list_read_4.f90.

[flang] Signal runtime error on WRITE after ENDFILE

After an ENDFILE statement, a WRITE is an error without
a prior BACKSPACE. Also fix the return value for the case
of formatted integer input with no input digits to be false
(exposed by new test).

[flang] Complete the fix for NAMELIST look-ahead case

When processing the devious NAMELIST input

&group logarray = t t t
= 666 /

for LOGICAL::logarray(3) and INTEGER::t, the runtime library
needs to do some look-ahead on the input stream to make sure
that the last "t" on the first line is a truth value rather than
an item name -- which in this case it is. This look-ahead
was implemented in a previous patch but only worked for internal
input cases; this patch implements look-ahead capabilities for
input from an external file, too (and also adjusts repeated
list-directed input items to use this infrastructure, too).
