context: move _manifest from committablectx to workingctx

committablectx had a _manifest implementation that was only used by the derived
workingctx class. The other derived versions, like memctx and metadataonlyctx,
define their own _manifest functions.

Let's move the function down to workingctx, and let's break it into two parts,
the _manifest part that reads from self._status, and the part that actually
builds the new manifest. This separation will let us reuse the builder code in a
future patch to answer _buildstatus with varying status inputs, since workingctx
has special behavior for _buildstatus that the other ctx's don't have.

  $ hg init
  $ echo a > a
  $ hg ci -Ama
  adding a

  $ echo b > b
  $ hg branch b
  marked working directory as branch b
  (branches are permanent and global, did you want a bookmark?)
  $ hg ci -Amb
  adding b

  $ hg co -C 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

Fast-forward:

  $ hg merge b
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -Ammerge

Bogus fast-forward should fail:

  $ hg merge b
  abort: merging with a working directory ancestor has no effect
  [255]

Even with strange revset (issue4465)

  $ hg merge ::.
  abort: merging with a working directory ancestor has no effect
