The flag enables a second power supply (VAPWR), not necessarily 3.3V (gf180's core is already 3v3), so "uses_3v3" no longer accurately describes its purpose.
Rename it across project_info, precheck, project and shuttle, and update the validation message accordingly.
The legacy "uses_3v3" key is still accepted when reading info.yaml, so existing project configs keep working.
The shuttle datasheet flow was updated to santise strings properly, and within the changes were some updates to the template that was used. This template is shared between the shuttle and individual projects, but the standalone version wasn't updated to be compatible. This commit rectifies that issue.

Up to this point, we relied on the PDK's default power pin names. However, the defaults names for GF180, VDD and VSS, are not compatible with Tiny Tapeout, which expects VPWR (or VDPWR) and VGND. So instead, we set the VDD_PIN and GND_PIN config options explicitly.
Each tech has a different metal stackup, so user projects get a different top routing metal layer. tt-support-tools now handles this instead of the user having to worry about this when switching PDKs.
Make the codebase more PDK-agnostic by moving tech-specific code to `tech.py` and tech specific files (e.g. def files, tile_sizes.yaml) to `tech/<pdkname>` subdirectory.
* fix(orfs): remove special handling of DRC error Pin.f.M5
* fix(orfs): remove patch for IHP PDK
We use our own fork now with the patch integrated.
* fix(orfs): allow updating ORFS platform files from IHP PDK

OpenLane 2.1.1 produces a verilog netlist with the power ports declared as "inout", where as 2.0.8 and earlier declared the power ports as "input". Change our scripts to accept "inout" as a valid direction for the power ports.
