Fix GCC error: extra ‘;’ [-Werror=pedantic] (#1295)

The macro `BGFX_HANDLE` is used the following way `BGFX_HANDLE(DynamicIndexBufferHandle);`, however it creates an error when using -Werror=pedantic with GCC since the `;` is unneeded.
I removed the `;` as I can't silence this warning without removing pendantic as a whole.
