[PRISM] Allow rest parameter to be `*`

Prior to this commit, if a rest parameters was `*`, we did not add
it to the locals table correctly. This commit fixes that.

[PRISM] Properly compile MultiTargetNodes within parameters
...
If there are MultiTargetNodes within parameters, we need to
iterate over them and compile them individually correctly, once
the locals are all in the correct spaces. We need to add one
getlocal for the hidden variable, and then can recurse into the
MultiTargetNodes themselves

[PRISM] Restructure parameters on ScopeNodes
...
This commit completely restructures how we handle parameters. The
motivation for this commit was the fix compilation of MultiTargetNodes
within parameters, including nested MultiTargetNodes. A subsequent
commit will actually do the compilation for the MultiTargetNodes.
This commit's main accomplishment is restructuring the locals table
and how we account for it on the ScopeNode, specifically with regards
to hidden variables.
It has multiple steps, all commented within the code, to calculate
the locals table correctly and compile the parameters:
- Step 1: Caculate the table size for the locals
- Step 2: Populate iv index table and local table
- Step 3: Fill in parameter names of MultiTargetNodes on local table
- Step 4: Fill in method body locals on local table
- Step 5: Compile any locals

[PRISM] Define and use a pm_add_ensure_iseq

Prior to this commit, we were using `add_ensure_iseq` which compiled
a node as if it was a CRuby node. This commit defines
`pm_add_ensure_iseq` which compiles the Prism node appropriately.

Add handling of implicit hash arguments
...
Arguments that are passed as a hash need special consideration since in certain case they are not treated as keyword arguments. For example, if a call is passing `"a" => 1` as an argument, this will be turned into an implicit hash argument and not a keyword argument.
The existing compiler checks to see if all hash nodes can be treated as keyword arguments. If they can, then it will treat them as keyword arguments. If not, then it will treat them as implicit hash arguments.
This commit implements the same logic inside the Prism compiler.

[PRISM] Fix `PM_CALL_NODE` assignment
...
This PR fixes ruby/prism#1963 . Array and variable assignment was broken
for call nodes. The change checks if the `method_id` is related to
assignment and if is adds a `putnil`, `setn` and a `pop`.
The incorrect instructions meant that in some cases (demonstrated in
tests) the wrong value would be returned.
I verified that this fixes the test mentioned in the issue
(run: `RUBY_ISEQ_DUMP_DEBUG=prism make test/-ext-/st/test_numhash.rb`)
Incorrect instructions:
