So far, calls to Wasm C/C++ API functions reused the call descriptors
of WasmImportWrappers, and the stack frame type of regular Wasm
functions. This CL cleans that up by introducing separate implementations
for both. No change in functionality or performance is expected.

On Android libraries there are zero length entries within the ranged
symbols which break our range processing. This updates the logic to
only add entries for zero-length entries if they aren't within the range
of the previously added entry.

On Android we load the native library directly from the APK. As such,
we need to convert symbols from the mapped APK to the underlying .so

This CL adds a --apk-embedded-library argument to tick processor to enable

symbolizing.

Macros are now inaccessible from CSA except if their declaration is
marked with the "export" keyword. The implicit field accessors for class
fields are always exported.
In this CL, unwarranted access from CSA is prevented by appending a
pseudo-random suffix to non-exported names. This is to be replaced by
something more principled, namely by not including these macros at all in
the headers included from CSA.

- Rename @ifdef to @if and add @ifnot for inverse checks
- Allow void fields in class declarations, which take up no space and
