[vm/compiler] Remove too conservative release assert, add boxed-field/unboxed-implicit-getter graph intrinsic support

The initial release assert was added when removing assembler intrinsics
for implicit getters and replacing them with graph intrinsics in:

  https://dart-review.googlesource.com/c/sdk/+/155900

Normally if the return value of a implicit field getter is unboxed, the
field itself must be unboxable. That is true, though just because we can
unbox a field doesn't mean we always will:

The unboxing field bitmap - which e.g. the GC uses - only allows 64-bits.
Classes with more fields might have some fields boxed even though they
could theoretically be unboxed.
