[vm] Free readonly header bit so it can be used for other uses.
...
This is reland of https://dart-review.googlesource.com/c/sdk/+/97340 rebased on top of removal of GraphMarked bit, which was not compatible with this ReadOnly->InVMIsolateHeap change(due to how write-pages are not covered by Contains check)

[vm] Free readonly header bit so it can be used for other uses.
...
Rely on vm_isolate()->heap()->Contains() instead of header bit check.

[vm] Mark VM isolate objects at heap finalization instead of allocation.
...
Avoids unnecessary branching in allocation.
Also, rename the VMHeap bit to ReadOnly to reflect its current usage.

[VM, Compiler] Move compiler to a separate folder.
...
New folder structure (nested under vm/):
- compiler/
- jit/ - JIT specific code
- aot/ - AOT specific code
- backend/ - all middle-end and back-end code (IL, flow graph)
- assembler/ - assemblers and disassemblers
- frontend/ - front ends (AST -> IL, Kernel -> IL)
compiler/README.md would be the documentation root for the compiler
