Reland "[vm/ffi] Add common C types"
We're adding these types to `dart:ffi` rather than `package:ffi` so that they can be used with `FfiNative`s. Adds `NativeType`s for the following C types: * unsigned char * signed char * short * unsigned short * int * unsigned int * long * unsigned long * long long * unsigned long long * uintptr_t * size_t * wchar_t Because the C standard only defines minimum sizes for many of these types, future platforms might diverge from the typical size even if all platforms currently agree on a size. To avoid having to reification later, we define all types as AbiSpecificIntegers rather than typedefs, even if all current target platforms agree on the size. Closes: https://github.com/dart-lang/sdk/issues/36140 TEST=tests/ffi/c_types_test.dart Original patch in patchset 1. * Removes `Char` for now until package:win32 has rolled to 2.3.8 in Flutter. https://pub.dev/packages/win32/versions/2.3.8/changelog https://logs.chromium.org/logs/flutter/buildbucket/cr-buildbucket/8824468064587445729/+/u/Android_Views_Integration_Tests/stdout * Adds `c_type.dart` in `ffi_source.gni` which should fix `IntPtr` missing when analyzing `path_provider_linux`.

[vm/ffi] ABI-specific integers
This CL adds support for users defining integers which are mapped to
differing sizes and signedness based on the application binary interface
the Dart VM is running on.
Notable implementation design decisions:
- ABIs are open world, so that adding an ABI to the Dart VM does not
break existing definitions. Thus, we only figure out in the VM that
we're missing a mapping. We throw compile-time errors.
- In AOT, these show up in the precompilation step.
- In JIT, these show up as `_CompileTimeError` at runtime. Note that
these can be caught. So in subsequent compilation steps we need to
ensure that we also throw the same compile-time error.
- We match on the call-sites (streaming_flowgraph_builder) rather than
method bodies (kernel_to_il) of AbiSpecific loads and stores so that
we can compile for the int-size of the call site.
API design decisions:

[vm/ffi] Add Bool
This CL adds the `Bool` `NativeType` with support for loading/storing from `Pointer<Bool>`, `Array<Bool>`, and `Struct` and `Union` fields, and support for passing booleans through FFI calls and callbacks. The assumption is that `bool` is always treated as `uint8_t` in the native ABIs. Including: (1) whether there can be garbage in the upper bytes in CPU registers, (2) stack alignment, and (3) alignment in compounds. The conversion from `bool` to `uint8_t` is implemented as follows: - bool to int: `value ? 1 : 0` - int to bool: `value != 0` The conversion is implemented in Dart in patch files for memory loads and stores (pointer, array, and struct fields) and kernel_to_il for FFI call and callback arguments and return value.

[test/ffi] Split generated files on isLeaf
Splits up tests/ffi/function_structs_by_value_generated_test.dart in - compounds - non-leaf calls - leaf calls We could also consider splitting on chunks from the `functions` from tests/ffi/generator/structs_by_value_tests_configuration.dart as a follow up.
