It should not be necessary to ever run `pub get` for a package which is
not published. All packages used in the SDK are controlled by a single
package config, so it's not necessary to declare versions or paths for
any packages.
Remove all dependency overrides.

Implements a backend targeting RV32GC and RV64GC, based on Linux standardizing around GC. The assembler is written to make it easy to disable usage of C, but because the sizes of some instruction sequences are compile-time constants, an additional build configuration would need to be defined to make use of it.
The assembler and disassembler cover every RV32/64GC instruction. The simulator covers all instructions except accessing CSRs and the floating point state accessible through such, include accrued exceptions and dynamic rounding mode.
Quirks:
- RISC-V is a compare-and-branch architecture, but some existing "architecture-independent" parts of the Dart compiler assume a condition code architecture. To avoid rewriting these parts, we use a peephole in the assembler to map to compare-and-branch. See Assembler::BranchIf. Luckily nothing depended on taking multiple branches on the same condition code set.
- There are no hardware overflow checks, so we must use Hacker's Delight style software checks. Often these are very cheap: if the sign of one operand is known, a single branch is needed.
- The ranges of RISC-V branches and jumps are such that we use 3 levels of generation for forward branches, instead of the 2 levels of near and far branches used on ARM[64]. Nearly all code is handled by the first two levels with 20-bits of range, with enormous regex matchers triggering the third level that uses aupic+jalr to get 32-bits of range.
- For PC-relative calls in AOT, we always generate auipc+jalr pairs with 32-bits of range, so we never generate trampolines.
- Only a subset of registers are available in some compressed instructions, so we assign the most popular uses to these registers. In particular, THR, TMP[2], CODE and PP. This has the effect of assigning CODE and PP to volatile registers in the C calling convention, whereas they are assigned preserved registers on the other architectures. As on ARM64, PP is untagged; this is so short indices can be accessed with a compressed instruction.
- There are no push or pop instructions, so combining pushes and pops is preferred so we can update SP once.
- The C calling convention has a strongly aligned stack, but unlike on ARM64 we don't need to use an alternate stack pointer. The author ensured language was added to the RISC-V psABI making the OS responsible for realigning the stack pointer for signal handlers, allowing Dart to leave the stack pointer misaligned from the C calling convention's point of view until a foreign call.
- We don't bother with the link register tracking done on ARM[64]. Instead we make use of an alternate link register to avoid inline spilling in the write barrier.
Unimplemented:
- non-trivial FFI cases
- Compressed pointers - No intention to implement.
- Unboxed SIMD - We might make use of the V extension registers when the V extension is ratified.
- BigInt intrinsics

This makes it an actual Pub package like most other code inside the SDK
repo. The main goal is to make it easier to write tests for the test
runner itself.
This change:
- Moves all of the code from tools/testing/dart/ over to
pkg/test_runner. Most of it ends up under test_runner/lib/src.
- Move tools/testing/dart/main.dart to
pkg/test_runner/bin/test_runner.dart.
- Move standalone_2/io/test_runner_test.dart to
pkg/test_runner/test/test_runner_test.dart. I don't think it currently
works, but it wasn't being run in its old location either.
- Add test_runner to the analysis-server bot. This ensures the
test_runner package is static error clean.
- Remove standalone_2/io/test_runner_analyze_test.dart which used to
attempt to do the above and is no longer needed.
- Update test.py to look for the test runner at its new location.
- Add test_runner to the repo .packages file and remove the weird
test_dart pseudo-package. (I think this fixes #35279.)
- Remove status file entries for the removed standalone_2 tests.
There are no code changes to the test runner itself aside from fixing
up import paths.

This adds support for BabelJS to test.py's dart2js compiler
configuration. When --babel is specified directly or through a named
configuration, test.py will run an additional step after dart2js that
post-processes the javascript output by running it through BabelJS with
the specified Babel configuration. BabelJS is added to the DEPS in its
standalone form. d8 is used to run BabelJS standalone to avoid adding
a dependency on NodeJS. d8 can only write to stdout but not to files or
stderr, which makes it necessary to change the test_runner to handle
commands that expect their output to be piped to a file.
Changes:
* Add --babel option to test.py.
* Add babel option to pkg/smith.
* Switch IE11 builder to use babel transformation.
* Fix option list comparison bugs in pkg/smith.
* Change dart2js compiler configuration to generate files using the
test name rather than just "out.js" (update test that relied on this).
* Remove runtime_configuration dependency on test_suite.
* Remove obsolete blocks adding --preview-dart-2 dart2js arguments.
* Make dart2js' compiler configuration more like DDC's.
* Remove createCommand method that is no longer used.
* Remove support for "OtherResources" which was only used for
dart:isolate tests on dart2js and DDC.
* Skip co19_2 tests that are slow to transform with babel.
* Simplify the timeout handling in the test runner with Future.timeout.
