… hooks to run during upgrade and clear out the asset builder cache post upgrade

Overview

This is an alternate to #19133 This aims to achieve the same result of a smooth upgrade by permitting the hook_civicrm_container running during the upgrade and some other hooks which might assist end users and also when I tested locally I found I couldn't create a new mosaico mailing after upgrade from 5.32 to 5.34 because aset builder cache was problematic so this clears it as well

Before

Error about undefined service

After

No error and smooth upgrade

@seamuslee001 Thanks. I built a tarball based on master (5.34-alpa) and 5.33 (5.33-RC) with the patch and upgraded two sites with the built in flexmailer and Mosaico 2.5

• r-run 5.33-RC to 5.34-alpha success
• r-run 5.30.0 to 5.33-RC success

This looks good to merge. I'd actually want to target 5.33 so it gets in the RC and then we can merge 5.33 to master.

@seamuslee001 I think rc would make sense - that gives us the option of backporting if we choose

[seamuslee001]

@eileenmcnaughton @kcristiano rebased onto the RC now

Thanks Seamus. I did another upgrade with this on a rebuilt 5.33-RC tarball and it works perfectly. I think it's good to merge

Nice - thanks @seamuslee001 - I think this will resolve a slow trickle of errors
