This change refactors `_asExternalTypedData` into multiple functions,
which are data type specific, e.g `_asExternalTypedDataInt8`.
These functions are implemented as recognized methods.
Argument checks have previously been performed in the removed
runtime entry implementation of `_asExternalTypedData.` These are
now handled in Dart.

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.

Adds support for single dimension inline arrays in structs. Multi-
dimensional arrays will be supported in a future CL.
This CL adds:
- CFE static error checks for inline arrays.
- CFE transformations for inline arrays.
- VM consumption of inline array fields for NativeType.
- Test generator support for inline arrays + generated tests.
Previous CLs added support for inline arrays in:
- analyzer https://dart-review.googlesource.com/c/sdk/+/183684
- updated in this CL to new API.
- ABI calculation https://dart-review.googlesource.com/c/sdk/+/183682
Closes: https://github.com/dart-lang/sdk/issues/35763
Open issue: https://github.com/dart-lang/sdk/issues/45101
CFE transformations are tested with expectation files:
TEST=pkg/front_end/testcases/(.*)/ffi_struct_inline_array.dart
Trampolines and CArray API are tested with end-to-end Dart tests:
TEST=tests/ffi(_2)/(.*)by_value(.*)test.dart
TEST=tests/ffi(_2)/inline_array_test.dart
Compile-time errors (both CFE and analyzer) are tested in:
TEST=tests/ffi(_2)/vmspecific_static_checks_test.dart
