Stop the bleed on chunk mapper panic (#8723) 
* Added test to reproduce panic on TSDB head chunks truncated while querying

Signed-off-by: Marco Pracucci <marco@pracucci.com>

* Added test for Querier too

Signed-off-by: Marco Pracucci <marco@pracucci.com>

* Stop the bleed on mmap-ed head chunks panic

Signed-off-by: Marco Pracucci <marco@pracucci.com>

* Lower memory pressure in tests to ensure it doesn't OOM

Signed-off-by: Marco Pracucci <marco@pracucci.com>

* Skip TestQuerier_ShouldNotPanicIfHeadChunkIsTruncatedWhileReadingQueriedChunks

Signed-off-by: Marco Pracucci <marco@pracucci.com>

* Experiment to not trigger runtime.GC() continuously

Signed-off-by: Marco Pracucci <marco@pracucci.com>

* Try to fix test in CI

Signed-off-by: Marco Pracucci <marco@pracucci.com>

* Do not call runtime.GC() at all

Signed-off-by: Marco Pracucci <marco@pracucci.com>

* I have no idea why it's failing in CI, skipping tests
