Add firmware support for new AMDC REV F hardware

[npetersen2]

We recently released a new AMDC hardware revision: REV20231005F, see the PR: https://github.com/Severson-Group/AMDC-Hardware/pull/228.

Per the last page of the schematics, the changes for this revision are rather small:

• Add termination on GPIO differential inputs
• Update pull-down resistor value for boot-up PWM output protection
• Update P/Ns and footprints for manufacturability

These require no functional changes to the firmware---the REV E firmware will work with the new REV F hardware!

Items to do

Even though users can simply use AMDC_REV_E firmware config to run the new REV F hardware, we should make REV F appear as "fully supported" in the docs and the firmware. This requires the following changes:

FPGA support

• [x] Copy the block diagram /hw/amdc_reve.bd to /hw/amdc_revf.bd and update any internal text to say "REV F" etc
• [x] Copy the constraints file /hw/constraints_amdc_reve.xdc to /hw/constraints_amdc_revf.xdc and update text to say "REV F" etc
• [x] Add a new /import_revf.tcl file which is a clone of the import_reve.tcl file, but with the variable proj_revision set to revf
• [x] Run the new import script in Vivado and confirm it works seamlessly

DSP support

• [x] Update drv/hardware_targets.h to add AMDC_REV_F define
• [x] Update the default hardware target USER_CONFIG_HARDWARE_TARGET to AMDC_REV_F in usr/user_config.h
• [x] Search the codebase for AMDC_REV_E and make any ifdefs also apply for AMDC_REV_F

Documentation support

See https://github.com/Severson-Group/docs.amdc.dev/issues/92

Note that these changes are targeting the v1 codebase and should be based off develop.

We will release this new REV F support as v1.2.0.
