The PR branch had merge conflicts with `devel` due to a major compiler
refactoring that extracted type definitions from `compiler/ast.nim` into
a new `compiler/astdef.nim` file.
## Changes
- Resolved conflict in `compiler/ast.nim` by accepting `devel`'s
refactored structure
- Merged 763 commits from `devel` branch (commit range:
`ce6a345..b3273e7`)
- Preserved original PR changes removing deprecated symbols from
`lib/core/macros.nim`
The core PR functionality (removal of deprecated macros API since
v0.18.1) remains intact while incorporating the upstream AST
refactoring.

fixes#24705
```nim
proc xxx(v: static int) =
echo v
xxx(10)
xxx(20)
```
They are mangled as `_ZN14titaniummangle7xxx_s10E` and
`_ZN14titaniummangle7xxx_s20E` with `--debugger:native`. Static
parameters are prefixed with `_s` to distinguish simple cases like
`xxx(10, 15)` and `xxx(101, 5)` if `xxx` supports two `static[int]`
parameters
