docs: J-Link commands added to the manual

The J-Link related commands and configuration commands were added
to the "8.2 Interface Drivers" section of the manual.
(previously they were enumerated as comments).
The 'jlink pid' was marked as Config all other as Command.
A draft of a compatibility note was added, but probably
a table would be more appropriate.

+@quotation Compatibility Note
+Segger released many firmware versions for the many harware versions they
+produced. OpenOCD was extensively tested and intended to run on all of them,
+but some combinations were reported as incompatible. As a general
+recommendation, it is advisable to use the latest firmware version
+available for each hardware version. However the current V8 is a moving
+target, and Segger firmware versions released after the OpenOCD was
+released may not be compatible. In such cases it is recommended to
+revert to the last known functional version. For 0.5.0, this is from
+"Feb  8 2012 14:30:39", packed with 4.42c. For 0.6.0, the last known
+version is from "May  3 2012 18:36:22", packed with 4.46f.
