Since Dart 2, library prefixes are always loaded eagerly on the VM.
Also remove reload check for deferred prefixes. This check was added to avoid behavior of library prefixes giving spurious "not loaded" errors after a reload, but now this error can never occur. Resolves a difference in reload between AST and bytecode modes, since bytecode mode isn't surfacing the deferred property.

This was triggered by 85360 which introduced external code observers
called during dart init.
The bug is however susceptible to racing as tests often shutdown the VM
before the code is fully deserialised.
Code::function() is deceptive as it does in fact not guarantee that its
return value is a Function. This in turn caused observer code to try access
non-exists members on not-actually-Functions.

Regressions in tests:
1) Test language_2/type_alias_equality_test/04 fails similarly to default mode, as VM
does not implement comparison of function types according to the specification.
Previously this test was passing as function types were canonicalized in bytecode,
which was not always correct. This CL fixes the problem with canonicalization of
function types in bytecode and the test starts failing again.
2) Tests standalone_2/entrypoints_verification_test, standalone_2/io/test_extension_test,
standalone_2/io/test_extension_fail_test fail as native extensions are not supported
in bytecode yet. These tests start passing after df5e7aac17,
which switched bytecode tests to kernel service (on x64), because kernel service doesn't
drop ASTs. This CL switches from reading AST library declarations to bytecode even if
AST is not removed, so tests fail again.

This moves the length field as well as an inner pointer to the start of
the data into the RawTypedDataBase class. The inner pointer is updated
on allocation, scavenges and old space compactions.
To avoid writing more assembly the typed data view factory constructors
will be generated using IL, which will update the inner pointer. This
required adding new IR instructions and changing the existing
UnboxedIntConverter instruction.
This is the foundation work to de-virtualize calls on the public typed
data types, e.g. Uint8List.

There are following regressions in bytecode mode, which will be fixed
in future:
* dart:mirrors are not supported yet (implementation of mirrors relies
on reading kernel AST in certain cases).
As the result, lib_2/mirrors/* tests fail.
* native extensions are not supported yet (annotations on libraries
and classes in AST are cleaned up as they could reference members
which are now removed from AST).
As the result, standalone_2/entrypoints_verification_test test fails.
* language_2/spread_collections/const_error_test/* tests fail
due to https://github.com/dart-lang/sdk/issues/36286.

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)
