base: make Foreign.Marshal.Pool use RTS internal arena for allocation

`Foreign.Marshal.Pool` used to call `malloc` once for each allocation
request. Each `Pool` maintained a list of allocated pointers, and
traverses the list to `free` each one of those pointers. The extra O(n)
overhead is apparently bad for a `Pool` that serves a lot of small
allocation requests.

This patch uses the RTS internal arena to implement `Pool`, with these
benefits:

- Gets rid of the extra O(n) overhead.
- The RTS arena is simply a bump allocator backed by the block
  allocator, each allocation request is likely faster than a libc
  `malloc` call.

Closes #14762 #18338.

Give better errors for code corrupted by Unicode smart quotes (#21843)

Previously, we emitted a generic and potentially confusing error during lexical
analysis on programs containing smart quotes (“/”/‘/’). This commit adds
smart quote-aware lexer errors.

Buglet in GHC.Tc.Module.checkBootTyCon

This lurking bug used the wrong function to compare two
types in GHC.Tc.Module.checkBootTyCon

It's hard to trigger the bug, which only came up during
!9343, so there's no regression test in this MR.

Refactor TyCon to have a top-level product

This patch changes the representation of TyCon so that it has
a top-level product type, with a field that gives the details
(newtype, type family etc), #22458.
