Branch coverage can't be enabled by a simple global flag, because this
causes problems when functions in an app-jit snapshot that didn't have
the flag enabled are compiled by a VM that has the flag enabled. In
particular, the coverage array will see a different set of token
positions, causing some important asserts to fail.

This region is mostly unused after loading, but it may be accessed again if
- Isolate.spawn is invoke with isolate groups disabled
- A secondary snapshot produced by splitting is loaded
- An external typed data in the snapshot is accessed (usually a kernel file)
- Likely other cases
Even if these cases did not exist, the region is often part of a shared library and so unable to be released independently.
madvise(DONT_NEED) on this region will cause the OS to release the memory in this region but keep the address space reservation and mapping. If it is touched again, it will be brought back in from the file. If it is not backed by a file, such as malloc memory, it will be brought back in as zeros and the program will likely fail.

`DART_EXTERN` in `dart_api_dl.h` was missing `__declspec(dllexport)` on
Windows, causing `Dart_InitializeApiDL` to not be visible.
Using `DART_EXPORT` instead doesn't work because the definitions added
by `DART_API_ALL_DL_SYMBOLS` do not support having a 'used' attribute.
Instead, define a `DART_EXPORT_DL` for these which is identical but
without the 'used' attribute.
Note that the precompiler `DART_SHARED_LIB` macro must be defined for
`__declspec(dllexport)` to be part of `DART_EXPORT`/`DART_EXPORT_DL`.
Also fixes `#define DART_EXTERN_C` to be `extern` in C. Without this,
the linker will see duplicate symbols for things `DART_EXPORT`ed when
the `dart_api_dl.h` is included in C files.

if the operation is not completed when the isolate shuts down

This change adds a finalizable state for the 'File' object so that

the callback to clean up the 'File' object.
