Python 3.10 improvements

[hugsy]

Description

Follow-up PR for #1133 but purely esthetic, no functional changes

Cleans up the code to make it more in comformance with Python 3.10 capabilities.

Replaces:

• type Union with |
• type Dict/Set/List/Tuple with dict/set/list/tuple
• Optional with | None
• if: ... elif... -> match

Fixes:

• gdb.events.*Event -> gdb.*Event
• GefHeapManager.malloc_align_address had its ceil lambda moved as a proper (nested) function

Lint:

• except: -> except Exception:
• removed a bunch of unused f-strings
• if not .. in .. -> if .. not in ..
• some short named variables renamed

I removed all comments because the PR is still draft and having those messes up how VSCode displays them directly into my code.

Don't review until ready
