Rearranged tag encodings, reserved suptype=0 for internal tags

Browse Source 
This was motivated by a discussion with a gh user, in which it was noted
that not having a reserved suptype for internal tags risks potential
issues with long-term future tag compatibility.

I think the risk is low, but, without a reserved suptype, it _is_
possible for a future tag to conflict with an internal tag in an older
driver version, potentially and unintentionally breaking compatibility.
Note this is especially concerning during mdir compactions, where we
copy tags we may not understand otherwise.

In littlefs2 we reserved suptype=0x100, though this was mostly an
accident due to saturating the 3-bit suptype space. With the larger tag
space in littlefs3, the reserved suptype=0x100 was dropped.

---

Long story short, this reserves suptype=0 for internal flags (well, and
null, which is _mostly_ internal only, but does get written to disk as
unreachable tags).

Unfortunately, adding a new suptype _did_ require moving a bunch of
stuff around:

  * Planned
  + Reserved
  ? Hypothetical

Some additional notes:

- I was on the fence on keeping the 0x30 prefix on config tags now that
  it is not longer needed to differentiate from null, but ultimately
  decided to keep it because: 1. it's fun, 2. it decreases the chance
  of false positives, 3. it keeps the redund bits readable in hexdumps,
  and 4. it reserves some tags < config, which is useful since order
  matters.

  Instead, I pushed the 0x30 prefix to _more_ tags, mainly gstate.

  As a coincidence, meta related tags (MNAME, MROOT, MRTREE) all shifted
  to also have the 0x30 prefix, which is a nice bit of unexpected
  consistency.

- I also considered reserving the redund bits across the config tags
  similarly to what we've done in struct/gstate tags, but decided
  against it as 1. it significantly reduces the config tag space
  available, and 2. makes alignment with VERSION + R/W/OCOMPAT a bit
  awkward.

  Instead I think would should relax the redund bit alignment in other
  suptypes, though in practice the intermixing of non-redund and redund
  tags makes this a bit difficult.

  Maybe we should consider including redund bits as a hint for things
  like DATA? DDKEY? BSHRUB? etc?

- I created a bit more space for file btree struct tags, allowing for
  both the future planned DDKEY, and BLOCK with optional erased-bit. We
  don't currently use this, but it may be useful for the future planned
  gddtree, which in-theory can track erased-state in partially written
  file blocks.

  Currently tracking erased-state in file blocks is difficult due to
  the potential of multiple references, and inability to prevent ecksum
  conflicts in raw data blocks.

- UATTR/SATTR bumped up to 0x600/0x700 to keep the 1-bit alignment,
  leaving the suptype 0x500 unused. Though this may be useful if we ever
  run out of struct tags (suptype=0x400), which is likely where most new
  tags will go.
