Add explicit symbol visibility macros to InstrProfData.inc (llvm#110732)

Add explicit symbol visibility macros to InstrProfData.inc

Annotating these symbols will fix missing symbols for InstrProfTest when
using shared library builds on windows with explicit visibility macros
enabled.
Add a empty fallback definition for LLVM_ABI macro so the code works in
compiler-rt.

This is part of the work to enable LLVM_BUILD_LLVM_DYLIB and plugins on
window.

```
llvm\lld-link : error : undefined symbol: public: void ValueProfData::deserializeTo(InstrProfRecord&,  InstrProfSymtab*)
>>> referenced by unittests\ProfileData\InstrProfTest.cpp:1372 void ValueProfileReadWriteTest_value_prof_data_read_write_Test::TestBody()
```
