`.npmignore` did not use to be copied into the directories of the monopackage,
leading to files that *ought* to have been excluded to not be excluded.

Remove the file from the list of files that doesn't get copied to fix this.

This fix is not along the lines of the method suggested in the linked issue,
but it does address the original problem.

Fixes #12292.

These changes (plus import changes) were necessary to make these tests pass on
the `v2-main` branch. Back-porting to `master` to (hopefully) reduce future
forward-merge pain.

The 'returns base construct info if no more specific info is present' test was
removed as is wasn't truly necessary, and does not work with V2, where Construct
comes from the `constructs` library instead of `core.Construct`.

Across the CDK repo, remove the usage of deprecated symbols.

These are going to be removed in CDKv2, and these changes make
the codebases on the two branches more aligned.

However, this does not remove *all* usages of deprecated symbols,
but only the changes that are backwards compatible.

If the installed node version is >= 14, use Node.js 14.x. Otherwise, use
Node.js 12.x.

This removes a default on the deprecated Node.js 10.x runtime.

BREAKING CHANGE: the default runtime of a `NodejsFunction` is now Node.js 14.x if the environment from which it is deployed uses Node.js >= 14 and Node.js 12.x otherwise.

We need this to have `jsii-rosetta` runs that try to translate READMEs
from submodules not crash (because it can't find the referenced fixture
files).

This is not a correct final state yet, but it makes the build not crash.

Hopefully allows aws/jsii#2712 to be merged.

The allowed values for `UntrustedArtifactOnDeployment` in the
`AWS::Lambda::CodeSigningConfig` resource type are 'Warn' and 'Enforce'.

This was incorrectly set in the CDK.
