Following commmit implements to standard makefile argument
"syn_properties" as well additional 3:

- syn_instances -> set_global_instance
- syn_location_assignments-> set_location_assignment
- syn_instance_assignments -> set_instance_assignment

The original foreseen only

- syn_properties -> set_global_assignment

Following brings possibility to specify in manifest in more detail for
example logilock regions.

In order to make the parameters compatible with quartus manifest
properties 'to' and 'region_id' can be now preprended by tilde (~) to
announce that the given value of the command shall be enclosed in
quotes. This is needed as it differs from parameter to
parameter. Example:

following does not need any quotes:

set_global_assignment -name IOBANK_VCCIO 3.3V -section_id 3A

but following does:

set_instance_assignment -name LL_MEMBER_OF "bst_sync:i_bst_sync" -to
"VfcHdApplication:i_VfcHdApplication|bran:i_bran|bst_sync:i_bst_sync"
-section_id "bst_sync:i_bst_sync"

Needed to setup certain global properties, as e.g.

set_global_assignment -name OUTPUT_IO_TIMING_FAR_END_VMEAS "HALF SIGNAL SWING" -rise

lib components are ignored during dependency search

in addition to original CLEAN_TARGETS this commits as well:

- a5_pin_model_dump.txt
- *.sld

Fix lattice diamond take2: Filter clean targets - Add only relevant stages for every tool

See merge request !18

Fix(?): Use context manager for writing Makefile, improve TestSuite on Windows

See merge request !19

These testcases are intended to provoke HDLMake
Errors, therefore not generating a synthesis Makefile.

Before making the Makefile write 'atomic' with
contextmanager, these Makefiles have been generated both
on Linux and Windows.
On Linux, the testsuite passed even then.
But on Windows, these Makefiles have been reported
as busy while the TestCase tried to delete the files.
This resulted in OsErrors.

TestSuite failing on Linux:
FAILED test_all.py::test_quartus035 - FileNotFoundError: [Errno 2] No such file or directory: '035quartus_err/Makefile'
FAILED test_all.py::test_quartus036 - FileNotFoundError: [Errno 2] No such file or directory: '036quartus_err/Makefile'
FAILED test_all.py::test_quartus037 - FileNotFoundError: [Errno 2] No such file or directory: '037quartus_err/Makefile'
FAILED test_all.py::test_quartus038 - FileNotFoundError: [Errno 2] No such file or directory: '038quartus_err/Makefile'

Probably this is because these testases SHALL NOT generate a valid
makefile.
Before 'atomizing' the Makefile write, these Makefiles have been
generated anyway, despite the detected and reported errors.

No funstional change. Not fully clean refactor.
TestSuite Still passing on Linux.

According to filtered clean targets list,
now only the used stages are added as clean
targets.

This change is somehow the result of the clean
target filtering, but seems OK.

According to filtered clean targets list,
now only the used stages are added as clean
targets.

This clean target was missing with the filter
added in previous commit.

Try to add <stage> and related <stage>.tcl to clean
targets only if <stage> is used in the given tool.

Lattice Diamond tool related changes need to be
adjusted in related testcase as well.

Lattice project file removal - purge - TCL command
was directly used in the Makefile target generation,
instead of using the already defined tcl command
string.

- Lattice MachXO2/3 FPGA devices have internal boot Flash
  that can be targeted via Jedec PROM file.

- To support FLASH/PROM file generation
  as a separate stage from bitfile generation

- Preventing project source file duplication
- prj_src remove -all seems to not remove .lpf fi
  le, therefore causes error when adding again.
- When creating the project file, Diamond automatically adds
  the .ldf file to project, it the file exists with the same
  name as the created project.
  Therefore causing error as duplicated file addition.
- lpf is not added, only a commented-out
  tcl command is generated to the files.tcl

- This is just a quick hack, to be improved later

For later use in Makefile generation

- When run from command line (win/powershell, win/cmd, linux/bash),
  adding files already in the project causes failure.
  The reason is that diamond tcl interpreter returns some
  unexpected value.
  Therefore the make command fails at sourceing files.tcl

- Manually starting diamond tcl console and sourcing the files.tcl
  directly there seems fine.

- As a workaround, adding pre-fileadd tcl command to remove all
  sources from the project

- Seem to cause issues with lattice batch mode if project file
  already exists

- diamond project file is genereted when running make anyway
