This patch allows high level clients to define an EvalContext method
which can derive a new context given a block and the base parent
context.
This allows users of the package to intercept evaluation before it
begins, and define additional variables and functions that are bound to
a single block.

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.
