doc: arrange search prefix documentation in a definition list

Having first a list of prefixes followed by detailed descriptions was
viable when we didn't have all that many prefixes. Now, arranging the
prefix descriptions in a definition list makes more sense.

While at it, include all the supported prefix forms, especially some
missing regex ones.

The **from:** prefix is used to match the name or address of the sender
of an email message.
The **to:** prefix is used to match the names or addresses of any
recipient of an email message, (whether To, Cc, or Bcc).
Any term prefixed with **subject:** will match only text from the
subject of an email. Searching for a phrase in the subject is supported
by including quotation marks around the phrase, immediately following
**subject:**.
If notmuch is built with **Xapian Field Processors** (see below) the
**from:** and **subject** prefix can be also used to restrict the
results to those whose from/subject value matches a regular expression
(see **regex(7)**) delimited with //.

The **attachment:** prefix can be used to search for specific filenames from:<name-or-address> or from:/<regex>/

the sender of an email message.

the specified directory and all its subdirectories recursively.
**path:""** matches messages in the root of the mail store and,
likewise, **path:\*\*** matches all messages.
The **folder:** prefix searches for email messages by maildir or MH id:<message-id> or mid:<message-id> or mid:/<regex>/

folder (which is the root in maildir++), other folder names always
start with ".", and nested folders are separated by "."s, such as
**folder:.classes.topology**. For "file system" maildir, the inbox is
typically **folder:INBOX** and nested folders are separated by
slashes, such as **folder:classes/topology**.
Both **path:** and **folder:** will find a message if *any* copy of thread:<thread-id>
that message is in the specific directory/folder. The **thread:** prefix can be used with the thread ID values that
are generated internally by notmuch (and do not appear in email
messages). These thread ID values can be seen in the first column
of output from **notmuch search**
