Recent changes to the human-readable rendering of outputs and console
values led to long integer values being presented in scientific
notation (e.g. 1.2345678e+07). While technically correct, this is an
unusual way to present integer values.
This commit changes the formatting mode to 'f', which never uses
scientific notation and displays integer values as a sequence of digits
instead (e.g. 12345678).
The console and output formatter previously displayed multi-line strings
with escaped newlines, e.g. `"hello\nworld\n"`. While this is a valid
way to write the HCL string, it is not as common or as readable as using
the heredoc syntax, e.g.
<<EOF
hello
world
EOF
This commit adds heredoc detection and display to this formatter,
including support for indented heredocs for nested multi-line strings.
This change affects the apply, console, and output sub-commands.
Use a slightly modified value renderer from terraform-provider-testing
to display values in the console REPL, as well as outputs from the apply
and outputs subcommands.

Note that this is technically a breaking change for the console
subcommand, which would previously error if the user attempted to render
an unknown value (such as an unset variable). This was marked as an
unintentional side effect, with the goal being the new behaviour of
rendering "(unknown)", which is why I changed the behaviour in this
commit.
