This patch adds support for block-based interpolation, so that
properties of blocks can be referenced in the current block and across
other blocks.
Previously, order-of-evaluation did not matter for blocks, and could be
evaluated in any order. However, now that blocks can refer to each
other, we split out this dynamic evaluation order into a separate
resolveBlock function.
Additionally, we need to support partial block evaluations - if block A
refers to property X of block B, when we should only evaluate property
X, and not the entire block. This ensures that we can safely evaluate
blocks that refer to other properties within themselves, and allows
sequences that would otherwise be co-recursive. We take special care in
this logic to ensure that each property is evaluated once *and only*
once - this could otherwise present inconsistencies with stateful
functions, and could risk inconsistent results.

Groups that contained other groups were not recursively resolved by
ReadTargets, which prevented output from --print from being useable as a
self-contained bake file.
This patch ensures that all groups that are referenced inside the bake
file are actually defined under the groups field. This has required a
substantial refactor, as previously only a single group was returned
from ReadTargets, notably, returning a map of groups, instead of a
slice.
This does introduce a small behavior change to the behavior of --print -
while previously, passing a group name to bake would return all the
targets of that group back as the default group, now only the name of
that group will be inserted into the default group, keeping the original
group intact. The impact of this can be observed in some of the changes
to the bake_test.go file.

Terraform includes a timestamp function to get the current time. go-cty
has imported a number of the timestamp functions to it's standard
library, however, this was one was not included.
This patch simply pulls in the TimestampFunc from Terraform's
internal/lang/funcs/datetime.go to allow easily fetching the current
time in bake.

Body.JustAttributes cannot distinguish between blocks and attributes for
JSON files, so the variable block could be included in the list of
attributes returned.
This patch ensures that JSON and HCL files behave the same way by
removing all known block types first, from the provided config schema
and then from a generated definitions schema.
Fixes#1051

This fix adds a restriction `[a-zA-Z0-9_-]+`
for target name. This is pretty much the same as the
container name restriction in moby.
