"New" launcher, bootstrap.xml compatible

[icex2]

Fundamentally re-think how launcher operates and
bootstrapping the games is managed and configured.

This brings it significantly closer to how the original
bootstrap is doing the job: launcher now utilizes the
data (structures) provided by the bootstrap.xml configuration
file. This creates compatibility with vanilla data dumps
and original stock images. Note that bemanitools does not
include any code or means to run DRM'd data, only decrypted.

But, this allows users to keep decrypted dumps as stock as
possible which means:

• No copying around of property files anymore
• Keep the modules/ folder with the binaries
• Have bemanitools binaries separate in the data
• No need to edit/customize the original configuration files

A list of key features of the "new" launcher:

• Boostrap games by following the configuration provided by
  stock game's bootstrap.xml files
• Custom launcher.xml configuration file that adds further
  launcher configurable features, composability of
  bootstrap.xml configuration(s) as well as configuration
  overriding/stacking of selected types of configurations,
  e.g. eamuse config, avs-config. The latter eliminates
  the need for modifying stock config files in the prop/
  folder
• Unified logging system: launcher and AVS logging uses
  the same logger, all output can now be in a single file
• Original features such as various hook types still
  available

Move everything to new launcher.xml configuration
files. Adjust the bootstrapping of launcher in the
.bat files. Features such as copying the default
props/ files to nvram are now handled by launcher.

Using the PATH variable, bemanitools binaries can
live in their own dedicated bemanitools/ subfolder
next to props/ and modules/ now. All original
binaries are expected to be kept in a modules/
folder like on stock data.

Due to the significant architectural changes, this also
breaks with any backwards compatibility to existing
launcher setups. Thus, users need to migrate by re-applying
the new configuration format and migrating their config
parameters accordingly.

Further migration instructions and updated documentation
will be provided upon release.

Remark: This is currently not rebased to #278 which is pre-work required for the major refactoring. Just the last two commits account for the actual refactoring work relevant in this PR. I will rebase accordingly to clean-up the history once #278 is merged.

These are still open TODOs and feedback that are not addressed by this PR but will be followed-up to once this is merged.

• Complete addressing concerns of Log system information #57
• add development build container
• rework logging system, issues with non-async logging and lagging the game (stdout and file must be written async),
  implement features such as log ration etc. as outlined by the bootstrap logging config
  • Address also current limitations of logging API (potentially breaking API compatibility), see also util: Add log_error to util/log which does not hard fail #13
• have some sort of migration guide to switch to the new launcher. part of that should be proper
  documentation about how to use the launcher the configuration xml file and what you can do
  with it with various use-case examples
• align layout of distribution files, different for games such as iidx, jubeat and sdvx
• config format with stacking and overriding doesn't work here:

        <nr_filesys __type="u16">16</nr_filesys>
        <nr_mountpoint __type="u16">1024</nr_mountpoint>

            <device __type="str">.</device>
        </root>

        <mounttable>
            <vfs name="boot" fstype="fs" src="D:/LDJ/contents/dev/raw" dst="/dev/raw" opt="vf=1,posix=1"/>
            <vfs name="boot" fstype="fs" src="D:/LDJ/contents/dev/nvram" dst="/dev/nvram2" opt="vf=0,posix=1"/>
            <vfs name="boot" fstype="nvram2" src="/dev/nvram2" dst="/dev/nvram" opt="nr_mirror=4"/>
        </mounttable>
    </fs>

vfs nodes are being replaced as they are not unique by node name -> add tag __replace="true" or something similar to
