[PATCH 08/16] tests: add a meson suite / make target per block I/O tests format

["Daniel P. Berrangé" <berrange@redhat.com>]

Currently each block format is classified as either 'quick', 'slow' or
'thorough' and this controls whether its I/O tests are added to the meson
suites 'block-quick', 'block-slow' or 'block-thorough'.

This suites are exposed the 'check-block' make target, accepting the
optional SPEED variable.

As we add more formats to the 'thorough' group, however, it becomes
increasingly large and time consuming to run. What is needed is a make
target that can exercise all tests for an individual format, regardless
of speed classification.

This makes use of the previous enhancement to mtest2make.py to introduce
new meson suites 'block-$FORMAT-optional', which translate to new top
level make targets 'check-block-$FORMAT'. These new targets always run
all tests and as such do not need the SPEED variable to be set, but are
not triggered by 'make check' or 'make check-block'.
