Since commit 887e9df0c7 (VS: Update v142 CL flag table for VS 16.10,
2021-06-04) we map several `/external:*` flags to their corresponding
`.vcxproj` elements. These elements were added to `cl.xml` in VS 16.10,
so filter them out in older VS versions. Add a field to the json flag
table format to specify the minimum version of VS needed for a given
mapping.
Issue: #22308
Run the command
python3 Source/cmConvertMSBuildXMLToJSON.py -t v142 \
'c:/.../MSBuild/Microsoft/VC/v160/1033/cl.xml'
To generate `v142_CL.json` locally. Manually move new and updated
settings over to `Templates/MSBuild/FlagTables/v142_CL.json`.
Revise the `/sourceDependencies[:directives]` table entries to properly
distinguish the two options (because one is a prefix of the other), and
to populate both `Generate*Dependencies` and `*DependenciesFile`.
The `-std:c11` option added by commit f7347f28c7 (MSVC: Record support
for C11 and c_restrict, 2020-08-09, v3.18.2~9^2) needs this flag table
entry to map in the VS IDE properly.
Issue: #21069
Apply the change from commit e0d6d01e52 (VS: Add flag table entry for
"permissive" flag to disable conformance mode, 2018-12-10) to the
v142 flag table.
Rather than the change from commit 584ad067ba (VS: Fix flag table entry
for -Qspectre, 2018-11-26), update the v142 flag table with an actual
flag for the negative form of the flag. Switch the entry order so that
the longer negative form is first.
Apply the change from commit f1223e34c6 (VS: Add v140 flag table entries
for `-Zc:inline[-]`, 2018-11-26) to the v142 flag table.
The documentation of this option [1] claims that the default is off, but
VS seems to use `-Zc:inline` by default if `RemoveUnreferencedCodeData`
does not appear in the `.vcxproj` file. Add the flag table entry to
allow use of the flag to be configured.

Apply the change from commit 44dc9fc48a (VS: Fix /analyze:log flag
mapping, 2018-11-26) to the v142 flag table.
The `/analyze:log` argument requires a value in the following argument.
Also drop the general `/analyze:` flag table entry so that such flags
will be passed through as plain additional options. This is necessary
because some such options have following values and some do not but
not all have `.vcxproj` elements to hold the values.
