[PATCH] Documentation/rtla: fix htmldocs build error by renaming common_options.rst

[Gopi Krishna Menon <krishnagopi487@gmail.com>]

Running "make htmldocs" generates the following build errors for
common_options.rst

Documentation/tools/rtla/common_options.rst:58: ERROR: Undefined substitution referenced: "threshold".
Documentation/tools/rtla/common_options.rst:88: ERROR: Undefined substitution referenced: "tool".
Documentation/tools/rtla/common_options.rst:88: ERROR: Undefined substitution referenced: "thresharg".
Documentation/tools/rtla/common_options.rst:88: ERROR: Undefined substitution referenced: "tracer".
Documentation/tools/rtla/common_options.rst:92: ERROR: Undefined substitution referenced: "tracer".
Documentation/tools/rtla/common_options.rst:98: ERROR: Undefined substitution referenced: "actionsperf".
Documentation/tools/rtla/common_options.rst:113: ERROR: Undefined substitution referenced: "tool".

common_options.rst is intended to be included by other rtla documents
and is not meant to be built as a standalone document. It contains
substitutions that are only resolved by other documents, so building it
independently results in 'undefined substitution referenced' errors.

Rename common_options.rst to common_options.txt to prevent Sphinx from
building it as a standalone document and update the include references
accordingly.

Note: reStructuredText substitutions -
https://www.sphinx-doc.org/en/master/usage/restructuredtext/basics.html#substitutions

Tested by running "make htmldocs" before and after the change,
verifying that no substitution errors are generated and the 
output renders correctly in browsers.
