Adds handling for multiple sanitizers using a multi option.

This includes:
- Warning users if they try to use a sanitizer on release builds
- Changing the optimization flag of RelWithDebInfo to get stack traces
- Adding more checks in case someone mis-types
- Adding option for clangs memory sanitizer though this throws an error
  at the moment

Adds the Python library TOML to the required packages list for RHEL /
Debian / Mac. Additionally, it bumps the SHA for MSVC deps to a version
with the required files

Reorganise RPM dependencies for slightly more clarity.

The version of python36-sip in EPEL produces a PyQt4 that segfaults
when an eventFilter is overridden in Python. So as to not introduce
any further custom rpms we build and package a private copy of PyQt4
for Python 3 builds on EL7

Adds enum 34 to the required user packages on RHEL-7 following the enum
conversion

Bumps the minimum CMake version to 3.13, this allows us to use
add_link_options on address sanitizers.
At the time of this commit 3.14 is available for RHEL7, and 3.15 for
Ubuntu. Windows requires 3.15 so in an ideal world we would just set our
minimum to that, but as it's not fully available we settle for the
earlier version at the moment.

Allow use of amongst other things: boost.python.numpy and
boost small_vector

It is no longer used.

MSVCSetup uses variables that can be set by ParaView to
configure the startup scripts.

The issue was in determining the icon file for the .desktop file. It
had assumed that the icon already existed. This assumes that the icon
file exists only with the "nightly" and "unstable" suffixes.

It was accidentally removed when removing the qtawesome
dependency as it was not directly included.

After finding [this
article](https://stackoverflow.com/questions/36358217/what-is-the-difference-between-option-and-set-cache-bool-for-a-cmake-variabl),
clean up the cmake configuration to use `option`.

Matches the windows installation and makes it easier to find
the application without having to open a terminal.

This also gets rid of the variable to separate out packaging the
workbench.

Add in missing ,,,,

This separates the mantidplot and mantidworkbench dependencies into
different branches. It does the same thing for (ubuntu) python2/3
dependencies. Ubuntu 16.04 is now specifically checked for with all the
other newer ubuntus being considered default. Also did significant
changes to ubuntu requirements to form them more closely to how rhel
requirements are.
