CI: various improvements (#3096) 
* CI: upgrade macOS runner to version 12 (Monterey)

* CI: upgrade actions/checkout to v3

* CI: remove retry logic for apt

The Linux runners on GitHub Actions already retries up to 10 times,
see:
6c93c24107/images/linux/scripts/base/apt.sh (L11-L12)

* CI: remove redundant `DEBIAN_FRONTEND=noninteractive` env

The Linux runners on GitHub Actions already sets this env variable,
see:
6c93c24107/images/linux/scripts/installers/dpkg-config.sh (L10)

* CI: remove redundant `HOMEBREW_NO_AUTO_UPDATE=1` env

The macOS runners on GitHub Actions already sets this env variable,
see:
6c93c24107/images/macos/provision/configuration/environment/bashrc (L26)

* CI: prefer shorthand flag of apt-get `--fix-missing`

* CI: install libjxl on macOS runner

* Update test suite's README.md

spngsave: ensure quantisation occurs last (#3073) 
* spngsave: ensure quantisation occurs last

i.e. after setting the metadata and phyiscal pixel dimensions,
since quantisation will overwrite the image.

* spngsave: avoid over-allocation of temporary buffer

For low-bitdepth write and palette-based output.

spngsave: name ICC profiles (#3068)

a minumum length of 1 (we use the same "icc" name as pngsave).

tiff2vips: avoid g_assert_not_reached in the default clause (#3064) 
Since that could terminate the application in debug builds. Also,

fa4b80b74b earlier quit of dzsave on kill 
We were only testing "killed" once for each strip of tiles. Check on each
tile as well to make set_kill() faster.

3081821636 revert dhint check 
We added a check that loader ->header() and ->load() methods set the
same dhint. This commit removes that check -- it's not possible to make
header and load match in all cases since images can take so many routes,
and can change between the two events.

If we see performance issues around inappropriate cache sizing again,
try to fix just those cases.
