lang/funcs: Update fileset() function to include path as separate first argument, automatically trim the path argument from results, and ensure results are always canonical with forward slash path separators
Reference: https://github.com/hashicorp/terraform/pull/22523#pullrequestreview-279694703

These changes center around better function usability and consistency with other functions. The function has not yet been released, so these breaking changes can be applied safely.

lang/funcs: Add fileset function
Reference: https://github.com/hashicorp/terraform/issues/16697

Enumerates a set of regular file names from a given glob pattern. Implemented via the Go stdlib `path/filepath.Glob()` functionality. Notably, stdlib does not support `**` or `{}` extended patterns. See also: https://github.com/golang/go/issues/11862

To support the extended glob patterns, it will require adding a dependency on a third party library or adding our own matching code.

Martin Atkins 135afaeb9c lang: "regex" and "regexall" functions
These existing upstream cty functions allow matching strings against
regular expression patterns, which can be useful if you need to consume
a non-standard string format that Terraform doesn't (and can't) have a
built-in function for.

Lars Eric Scheidler aa07806bfc lang/funcs: New "uuidv5" function
This generates name-based uuids, rather than pseudorandom uuids as with the
"uuid" function.

Martin Atkins 382e1ca821 lang: yamldecode and yamlencode functions
These follow the same principle as jsondecode and jsonencode, but use
YAML instead of JSON.

YAML has a much more complex information model than JSON, so we can only
support a subset of it during decoding, but hopefully the subset supported
here is a useful one.

Because there are many different ways to _generate_ YAML, the yamlencode
function is forced to make some decisions, and those decisions are likely
to affect compatibility with other real-world YAML parsers. Although the
format here is intended to be generic and compatible, we may find that
there are problems with it that'll we'll want to adjust for in a future
release, so yamlencode is therefore marked as experimental for now until
the underlying library is ready to commit to ongoing byte-for-byte
compatibility in serialization.

The main use-case here is met by yamldecode, which will allow reading in
files written in YAML format by humans for use in Terraform modules, in
situations where a higher-level input format than direct Terraform
language declarations is helpful.

Martin Atkins f9a73d48db lang: "range" function
This is similar to the function of the same name in Python, generating a
sequence of numbers as a list that can then be used in other
sequence-oriented operations.

The primary use-case for it is to turn a count expressed as a number into
a list of that length, which can then be iterated over or passed to a
collection function to produce that number of something else, as shown
in the example at the end of its documentation page.

Kristin Laemmert 30a924e162 lang/funcs: `matchkeys` - unify type for keys and searchset
Added higher-level test for matchkeys to exercise mixing
types in searchset. This had to be in the functions tests so the HCL
auto conversion from tuple to list would occur.

lang/funcs: remove sethaselement function and documentation (#21164)
`contains` and `sethaselement` are effectively the same function, and
`contains` works with `sets` thanks to automatic HCL conversion.

James Bardin 19bddee11b more precise types handling in coalescelist
coalescelist should accept lists and tuples, and return a dynamic types
when the arguments are not homogeneous.

* lang/funcs/flatten: accept sets and tuples, return tuples
* lang/funcs: flatten should handle sets and tuples

* flatten now returns a tuple

lang/funcs: add acc tests for functions (#21112)
* lang/funcs: testing of functions through the lang package API
The function-specific unit tests do not cover the HCL conversion that happens when the functions are called in a terraform configuration. For e.g., HCL converts sets to lists before passing it to the function. This means that we could not test passing a set in the function _unit_ tests.
This adds a higher-level acceptance test, plus a check that every (pure) function has a test.

* website/docs: update function documentation
